Acts17apologetics protest to Allah; why allow corruption of previous scriptures?

In answer to the video "Answering Islam 12: What Does the Quran Say about the Bible?"

The discontinuation of the line of prophethood is among the reasons that necessitated the protection of the final revelation to mankind, a revelation containing all previous books 98:2-3 as here reflected in the declaration of faith

2:177"believe in Allah and the last day and the angels and the Book and the prophets".  

3:23,5:44,4:44,51"Have you not considered those to whom a portion of the Book has been given? They buy error and desire that you should go astray from the way".

This indicates that the Torah and Injil were not the final words of God, but portions of one Book 6:156. The Quran in fact uses that established pattern of continuous revelation, to comfort the prophet, telling him that should his adressees disbelieve in that same pattern that is now bestowed upon him, then let him now, people preceded him that wholeheartedly believed in it. Further, their rejection does not compromise the honor and credibility of that lofty institution of prophethood. Instead of grieving, or even doubting, the prophet should follow the guidance of his predecessors who held fast by the revelation that came to them 6:84-90. All previous revelations are part of one Book called the Mother of the Book/umm al kitab which the Quran is also part of

43:4,13:39,2:236"and remember Allah's favour to you, and that which He has revealed to you of the Book".

The previous revelations forecasted the final revelation in the form of the Quran 4:47. This draws attention to an important truth: all the revealed scriptures contain the same spiritual and moral principles. They cannot contradict eachother and their only differences reside in that they were made to conform to the language of the addressees

26:192-6"And most surely this is a revelation from the Lord of the worlds. The Faithful Spirit has descended with it, Upon your heart that you may be of the warners, In plain Arabic language. And most surely the same is in the scriptures of the ancients".

The Quran then verifies the truth of these divine portions of the one Book and offers a clear global explanation of it

10:37,20:133"Has not there come to them a clear evidence of what is in the previous books?".

This is why it is said to be the Guardian and Arbitrer/Muhaymin and a clear explanation of THE Book (singular) of which past scriptures including the Quran are part of 5:48-9,10:37. This single scripture containing all past revelations as well as the Quran is said to be highly secure, purified and preserved, exalted and honored, inaccessible to evil interference and only between the hands of the most honourable custodians 26:193,56:77-80,80:13-16,81:19-21,88:22. It has been engraved in the lawh mahfuz/the preserved tablet 85:21-2, hence it being referred to in the opening verses of sura baqara as it is dhaalika al kitab/that book or writing, denoting distance through the pronoun, because its katb/writing is done in a far heavenly place. In contrast the Quran speaks of this/hadha al Quran denoting closeness because its recitation is being done in this world. Another instance of the Quran's surgical use of words.

The Quran, being from the same God and containing the same basic wisdom and truths of ancient scriptures 6:91,26:196,29:46 speaks highly about the Torah and Injeel. They are referred to as sources of mercy, wisdom, guidance and light 5:43,44,46,7:154,11:17,28:43,46:12 as well as criterions of truth and falsehood (furqan) clarifying all things 2:53,21:48,28:43,37:117. It even cites them sometimes as sources of guidance hand in hand with the Quran 28:48-9. Because again, they are never said to be totally corrupted. Read with the knowledge of the Quran, whose function is to be the muhaymin/protector and arbitrer, one can discern the guiding parts of previous oral and written traditions from the portion that were corrupted, either purposefully or through neglect. 

In 46:12 it says the Torah came prior to the Quran, as a guide and mercy. It is this guiding and merciful aspect of the Torah that the statement musaddiqan/declaring true, refers to, not simply the Torah. It doesnt say declaring "it" true. This is seen by the rest of the verse, paralelling the guidance and mercy of the Torah with the Quran being a warner and giver of glad tidings. Again we see, the Quran only confirms the truthful aspects of past oral and written traditions, which the Quran never claims were entirely blotted out. This restricted aspect of the Quran's confirmation of the Torah is made clear in 6:154-7. The passage starts again with a praise of the Torah as being a book of mercy and guidance, followed by a parallel statement about the Quran, echoing stricly the merciful and guiding aspect of the Torah

"And this is a Book We have revealed, blessed; therefore follow it and be God-conscious that mercy may be shown to you".

The Torah contains many things that are neither guiding, nor sources of mercy, and other things that erroneous or even outright blasphemous about God and His prophets. The Quran does not confirm these things, and sometimes openly rejects them.

 The Quran condemns only the people that write the scriptures and manipulate it with their own hands. This is one of the miraculous qualities of the Quran, where it never assaults the Torah or Injeel in the context of corruption, but it lays blame always on the scribes. The Torah and Injeel are revealed by God, and considering the Torah and Injeel are from the same source as the one who revealed the Quran, it is only natural that the Quran never attacks the text per say. 

The Quran is therefore the official preserver of the Book and this means that if something is claimed to be in the Book but the Quran says otherwise, then it is not from the Book. If the Quran is silent then it may or may not be of the Book and if the Quran approves it then it certainly is part of the Book. Furthermore, an important Quranic axiom is that every fragment of revelation is fully revelation. A single word or verse of the Quran is called kitab and Quran. So is the case with Torah and Injil. A single genuine passage of any of these 2 revelations can be termed kitab and Torah or Injil. That is why when it urges the Jews to stand by the Torah and the Christians to stand by the Injil, it does not necessitate the totality of these books is endorsed by the Quran.

A long time ago, the prophet Muhammad explained how to approach the previous scriptures and traditions

“Do not believe the people of the Book, nor disbelieve them. Say: We have faith in Allah, in what has been revealed to us and what has been revealed to Abraham, Ishmael, Isaac, Jacob, and the tribes of Israel, in what was given to Moses and Jesus, and in what was given to the prophets from their Lord. We make no distinction between any of them, and we are Muslims surrendering to Him (2:136)”.

This hadith encapsulates the notion of muhaymin/arbitrer. Muslims unambiguously believe in what was revealed to the prophets 4:136. However, Muslims do not believe nor reject the current scriptures and traditions of the people of the book. This is because by rejecting them, they could inadvertently reject an authentic remnant of the teachings of the prophets. By believing in them on the other hand would carry the risk of accepting things that were never sent by God, nor approved by the prophets. The perfect way for Muslims to maintain the middle ground and not commit any faulty judgement would therefore be to hold fast by the Muhaymin/the arbitrer that has preserved the truth of the previous revelations. This reflects even in the attitude of the classical exegetes. They exhibited no interest in the Jews and Christians of whom they must have had some contemporary knowledge. With very few exceptions such as Ibn Kathir and Zamakshari, we find no reference to the varieties of Jewish and Christian belief and practices.

After declaring its status as the Guardian and Watcher, the Quran states that those legitimate differences between the scriptures that are not the subject of human corruption, were because the laws were subject to their respective time frames

"for every one of you did We appoint a law and a way".

Allah could have prescribed one and the same Law for all, making all of humanity into a single nation but He did not do so for many good reasons. One of these reasons is to test people whether they obey or not what is given to them. Those people, who understand the real nature and spirit of the Divine Way and the position of the regulations in it and are not prejudiced, will recognize and accept the Truth in whatever form it comes.

Such people will never hesitate to submit to the new regulations sent by Allah to replace the former ones. To demonstrate the unbiased nature of the Quranic message, it even tells its prophet in a hypothetical scenario that should a revelation be sent from God superseding both the Quran and the Torah, then Muhammad should be the first to follow it and nothing else 28:48-9. 

This verse isnt arguing from the angle of authenticity, that the new scripture supersedes the previous due to them being flawed. Neither does it give an indication as to whether one of the 2 is partially flawed while the other is pristine. The verse is arguing from the viewpoint of unconditional obedience to God, regardless of the level of authenticity of the current scriptures. Those, who do not understand the true spirit of the Way, but consider the regulations and their details alone to be the Way and who have become static and prejudiced because of their own additions to it, will reject every new thing that comes from Allah to replace what they already possess

5:48"and if Allah had pleased He would have made you (all) a single people, but that He might try you in what He gave you, therefore strive with one another to hasten to virtuous deeds; to Allah is your return, of all (of you), so He will let you know that in which you differed"  

22:67"therefore they should not dispute with you about the matter".

But the unbiased, who understand that God's guidance is indiscriminate, not only accept the new revelation but also

13:36"rejoice in that which has been revealed to you".

They read the book 2:121"as it ought to be read". Consequently they cannot but recognize it as the truth 4:162,5:83.
Just like when the Bani Israil were ordered to follow the Injeel when it was revealed, the same proclamation is made regarding the Quran, now that it has been revealed. It guides them out of the labyrinths of assumptions and conjectures

27:76"Surely this Quran declares to the children of Israel most of what they differ in".

It brings them back to the path they deviated from, when they failed upholding both the Torah and the Injeel 5:66. The only way they can rightly say that they are following their own scriptures is by believing in the Quran as well because these revelations are interconnected:

5:68"Say: O followers of the Book! you follow no good till you keep up the Taurat and the Injeel and that which is revealed to you from your Lord; and surely that which has been revealed to you from your Lord shall make many of them increase in inordinacy and unbelief; grieve not therefore for the unbelieving people". 

5:69"If only they had stood fast by the Law, the Gospel, and all the revelation that was sent to them from their Lord, they would have enjoyed happiness from every side. There is from among them a party on the right course: But many of them follow a course that is evil."

2:89-93"..but when there came to them (Prophet) that which they did recognize, they disbelieved in him; so Allah's curse is on the unbelievers. Evil is that for which they have sold their souls-- that they should deny what Allah has revealed, out of envy that Allah should send down of His grace on whomsoever of His servants He pleases..And when it is said to them, Believe in what Allah has revealed, they say: We believe in that which was revealed to us; and they deny what is besides that, while it is the truth verifying that which they have. Say: Why then did you kill Allah's Prophets before if you were indeed believers? And most certainly Musa came to you with clear arguments, then you took the calf (for a god) in his absence and you were unjust. And when We made a covenant with you and raised the mountain over you: Take hold of what We have given you with firmness and be obedient. They said: We hear and disobey. And they were made to imbibe (the love of) the calf into their hearts on account of their unbelief Say: Evil is that which your belief bids you if you are believers"

Acts17apologetics exercize their Arabic; Quran declaring Bible true?

In answer to the video "Answering Islam 12: What Does the Quran Say about the Bible?"

The reoccurring phrase musaddiqan lima bayna yadayhi/declaring true what is before it, is always preceded by a word refering to the Quran either directly as in 10:37"this Quran" or indirectly as in 12:111"this narrative" or 3:3,5:48"this book". It is the Quran in itself that declares the truth of what is before it. Not by pointing to a specific book or tradition and declaring it true, which it never does, but by selecting elements from what came before it, then stating the truthful version. 

What agrees with it, from whatever source that came before it, is then declared as truly from God and what disagrees with it is truly not from God. Then through its function as a protector of what came before it, the Quran brings back to light what was entirely forgotten or purposefully obscured in the chaotic transmission process of these oral and written traditions.

The phrase bayna yadayhi, lit. between his hands, is an old Arabic metaphor implying presence, availability of several things at the same time. It does not imply concrete, physical presence of the things in question, rather their knowledge or information. It is often translated as "what is before it" in the context of the Judeo-Christian traditions because they were present, whether orally or written in the time of the prophet, and they preceded him in existence. 

Many have taken this metaphor as refering specifically to the Torah or the Injil, although it never states so. It speaks of "what is between his hands" in a general sense, all that was available. Whether that information was canonized or not is irrelevant. So there is a truth, present in the time of the Quran and before, scattered in oral and written tradition, which the Quran declares to be true. It is the common thread that the Quran shares with all these contemporary and previous sources. 

To further corroborate, in 5:48-9 above, it is the only place where it explicitly says what it is refering to with the general statement "between his hands". In this context where it speaks of, and names the scriptures of the Jews and Christians, it would have been the perfect occasion for it to point to the Torah and Injil by name, had the expression been a reference to them both specifically, anytime it is used. Instead of that it points to PART OF/MIN THE Book in the singular

"musaddiqan lima bayna yadayhi MINAL kitab/declaring true what is before it OF the Book".

It doesnt even say part of the books in the plural, in reference to both Torah and Injil present at the time. The passage opposes 2 Books -Torah and Injil- to one Book which the Quran confirms and guards. It is different to every other context where the Quran says Jews and Christians follow one book. This is because they both read one Bible from their perspective, not many, and the Quran does not name their different books in these passages, contrary to the singular Book which is contrasted to the Torah and Injil in 5:48-9.

This singular book is thus the very one repeatedly alluded to, of which past scriptures and traditions, including the Quran, the Torah and Injil, are part of. A section of this global Book was revealed prior to the Quran, and was present in the time of the Quran, scattered in both written and oral tradition. It is this section previously revealed, of this global Book that the Quran guards, protects, confirms.

The Quran is that against which anything oral or written, claiming spiritual truth can be measured. It is al-Mizan -the Balance- and al-Furqan -the Criterion/distinguisher 25:1,42:17. It gives weight to the Truth and seperates between it and falsehood. The Quran is therefore the official preserver of the Book and this means that if something is claimed to be in the Book but the Quran says otherwise, then it is not from the Book. If the Quran is silent then it may or may not be of the Book and if the Quran approves it then it certainly is part of the Book. Furthermore, an important Quranic axiom is that every fragment of revelation is fully revelation. A single word or verse of the Quran is called kitab and Quran. So is the case with Torah and Injil. A single genuine passage of any of these 2 revelations can be termed kitab and Torah or Injil. That is why when it urges the Jews to stand by the Torah and the Christians to stand by the Injil, it does not necessitate the totality of these books is endorsed by the Quran.

Acts17apologetics agree with Quran; Bible is authentic?

In answer to the video "Answering Islam 12: What Does the Quran Say about the Bible?"

Now we get to the verse supposedly endorsing the current Bible's authenticity

5:47"Let the people of the Gospel judge by what Allah hath revealed therein. If any do fail to judge by (the light of) what Allah hath revealed, they are (no better than) those who rebel"

While in the present tense, is actually a describing past events. The whole passage from v43 to v47 follows the same pattern and culminates with the new reality, the superseding of the previous sytems with the latest revelation, the Quran. This is a common feature of classical Arabic, where tenses are often shifted for rhetorical purposes, and do not necessarily imply the respective time frame. For example, the Quran says that Allah kaana/was mighty, wise, forgiving, merciful 48:7,14 to mean that these attributes "are ever" with Allah or in 17:67 it is said that man kaana/was ungrateful to convey the idea of a persistent trait found in him. The Quran also refers to events that happen ON the Day of Judgement in the PAST TENSE, conveying the notion of inevitability of the events happening. The usage is still present in common speak when conveying the idea of certainty.

The passage thus starts at v43 and condemns the attitude of the Jews in Muhammad's time, bringing their internal matters to him for judgement, while they disbelieve in him, instead of upholding the scriptures in their hands which they claim is the absolute truth

5:43"And how do they make you a judge and they have the Taurat wherein is Allah's judgment?".

This rethorical question points to their straying throughout their history, and following their low-desires although they had the guidance from Allah with them all the time. To make them heed the portent of this sinful attitude, the Quran reverts to the past in 5:44 with the revelation of the Torah and reminds them how the successive prophets raised from among them based all their judgements on it

"for those who were Jews".

These judgements were only intended for the Israelites, and were never meant to have universal validity. They were therefore bound to judge by what Allah had revealed to them

5:44"and whoever did not judge by what Allah revealed, those are they that are the unbelievers".

Then verse 45 gives an example of a law they did everything to circumvent and manipulate through hairsplitting conjecture, so as to render it inapplicable, the law of retribution. It emphasizes that these people had no choice but to judge by what Allah revealed

5:45"and whoever did not judge by what Allah revealed, those are they that are the unjust".

This attitude towards their own books which they claimed to uphold against all others, was one that they had in the prophet's time. They often came to him seeking judgement in matters that were clearly defined in their own books, hoping for a different ruling. To illutrate that hypocrisy further, the Quran in v46 reminds them of the revelation of the Injeel to Jesus as a confirmation of the Torah and the next verse 47 is again a statement in the past, telling them they were bound by the Injeel when it was revealed, not simply what is in the Torah, which they had already distorted by that time. This is precisely why certain famous translators like Shakir, when translating this verse as he did with the preceding ones, uses the past tense, though the Arabic is in the present tense

5:47"And the followers of the Injeel should have judged by what Allah revealed in it; and whoever did not judge by what Allah revealed, those are they that are the transgressors".

The sequence of events, revelation of the Torah; Jews are bound by it, then revelation of the Injeel confirming the Torah; Jews and Christians are bound by it, then revelation of the Quran confirming Torah and Injeel; Jews, Christians and Muslims are bound by it. The sequence thus leads to the last revelation sent to humanity, in a series of revelations and now all mankind is bound to judge by it:

5:48-49"And We have revealed to you the Book with the truth, declaring true what is before it/musaddiqan lima bayna yadayhi of the Book and a guardian (Muhayminan) over it, therefore judge between them by what Allah has revealed, and do not follow their low desires (to turn away) from the truth that has come to you; for every one of you did We appoint a law and a way..And that you should judge between them by what Allah has revealed, and do not follow their low desires, and be cautious of them, lest they seduce you from part of what Allah has revealed to you.."

The final revelation has now descended in the form of the Quran:
1. It CONFIRMS the truth of what came before it
2. It GUARDS what came before it. The term Muhayminan, derived from H-M-N means witness and arbiter where the arbiter would be the one to let know which is right and wrong. Besides witnessing and arbitrating it carries at the same time the notion of protecting. So, when the book that came to Muhammad is declared as muhayminan upon the book it means it is the ultimate arbiter in case of dispute or potential misunderstanding in regards to whatever came before it. It declares what truly came from God vs what truly is not from God

45:16-8"And We did certainly give the Children of Israel the Scripture and judgement and prophethood, and We provided them with good things and preferred them over the worlds. And We gave them clear proofs of the matter [of religion]. And they did not differ except after knowledge had come to them - out of jealous animosity between themselves. Indeed, your Lord will judge between them on the Day of Resurrection concerning that over which they used to differ. Then We put you, [O Muhammad], on an ordained way concerning the matter [of religion]; so follow it and do not follow the inclinations of those who do not know". 

We see the same pattern of Allah revealing a system, those supposed to uphold it end up turning away from it, in addition causing its corruption. Hence the need for the religion to be restored through the revelation of a new system.

Acts17apologetics seek evidence; Quran verses challenging Bible authenticity?

In answer to the video "Answering Islam 12: What Does the Quran Say about the Bible?"

3:78"There is among them a section who distort the Book with their tongues: (As they read) you would think it is a part of the Book, but it is no part of the Book; and they say, "That is from Allah," but it is not from Allah. It is they who tell a lie against Allah, and (well) they know it" 

6:91"the Book which Musa brought, a light and a guidance to men, which you make into scattered writings which you show while you conceal much".

Just to corroborate what this verse is saying, The rabbinical world is divided up to this day on whether their sacred texts should be shared with non-Jews. There is consensus that non-Jews may study the Torah as far as the noachide laws are concerned. These laws are considered binding on all of humanity. The mosaic laws on the other hand concern strictly the Jewish people, hence the oddity of Pauline doctrine and its obsession with freeing mankind from a cursed law that isnt binding on anyone but Jews. Rabbinic opinion suggest that besides the noachide laws, only general and vague answers may be provided to a non-Jew inquiring about the Torah. The prohibition is discussed in the Talmud, which is considered God-given to Moses. The Talmud itself is on a higher level of restriction with even Jewish women forbidden from attempting to learn it due to the household activities they are expected to fulfill

2:75"but when they find themselves alone with one another, they say. "Do you inform them of what God has disclosed to you, so that they might use it in argument against you, quoting the words of your Sustainer?"  

3:187"And when Allah made a covenant with those who were given the Book: You shall certainly make it known to men and you shall not hide it; but they cast it behind their backs and took a small price for it; so evil is that which they buy".

2:75-79 "..and a party from among them indeed used to hear the Word of Allah, then altered it after they had understood it, and they know (this)..And there are among them illiterates, who know not the Book, but only lies, and they do but conjecture. Then woe to those who write the Book with their own hands, and then say:"This is from Allah," to traffic with it for miserable price!--Woe to them for what their hands do write, and for the gain they make thereby".

The Quran in those verses points to several types of misusing the scriptures;

-those who conceal the greater part of the book, reluctantly sharing as little as they can 6:91

-those who throw it completely behind their backs, ignoring it so as to not compromise some worldly profit. In the process, they are also guilty of failing to make it known to the world, as per their function of being the torch bearers of the truth to mankind 3:187.

-those who misinterpret the word of Allah after having fully understood it 2:75. Whether that information was canonized or not is irrelevant. This misinterpretation thus concerns both oral and written material. In Medina, members of the Jewish community were sent to the prophet Muhammad, by their religious authorities, with a hidden agenda. They were trying to settle grave disputes in matters heavily punishable in the light of the Torah. This was just another of their ploys to avoid its harsh laws, which they perfectly understood, hoping that the prophet might have a different ruling 

"they alter the words from their places, saying: If you are given this, take it, and if you are not given this, be cautious".  

This compromising, complacent attitude is a deeply ingrained transgression they have been committing ever since the law was bestowed upon them and throughout their history, despite the scolding of the prophets and the few righteous remnants among them whom the Quran mentions and praises 

7:169-170"Then there came after them an evil posterity who inherited the Book, taking only the frail good of this low life and saying: It will be forgiven us. And if the like good came to them, they would take it (too). Was not a promise taken from them in the Book that they would not speak anything about Allah but the truth, and they have read what is in it; and the abode of the hereafter is better for those who guard (against evil). Do you not then understand? And as for those who hold fast by the Book and keep up prayer, surely We do not waste the reward of the righteous"  

Virtually all prophets that came to them decried the corruption of their elite, their neglect towards their own justice system. Yet the prophet was not under any obligation to judge their matters when their intent was to use him as a pawn for their low desires 5:41-43. The prophet was nevertheless commanded to judge between them with equity should he decide so, notwithstanding their severe enmity towards him and the fact they were always plotting with the enemies of Islam with the hope of uprooting and exterminating it. One famous incident is that of 

"A Jew and a Jewess were brought to Allah's Apostle on a charge of committing an illegal sexual intercourse. The Prophet asked them. "What is the legal punishment (for this sin) in your Book (Torah)?" They replied, "Our priests have innovated the punishment of blackening the faces with charcoal and Tajbiya." 'Abdullah bin Salam said, "O Allah's Apostle, tell them to bring the Torah." The Torah was brought, and then one of the Jews put his hand over the Divine Verse of the Rajam (stoning to death) and started reading what preceded and what followed it. On that, Ibn Salam said to the Jew, "Lift up your hand." Behold! The Divine Verse of the Rajam was under his hand. So Allah's Apostle ordered that the two (sinners) be stoned to death, and so they were stoned. Ibn 'Umar added: So both of them were stoned at the Balat and I saw the Jew sheltering the Jewess".  

According to another version, when the Torah was brought to the prophet who was now seeking to expose the innovations of the rabbis in the specific matter of punishment for adultery, he first respectfully put it on a cushion then said 

"I believed in you and in Him Who revealed you". 

 A holistic understand of both the hadith corpus and the Quran demonstrates that this statement of the prophet is not to be taken in the absolute sense. When in Medina he noticed that Jews would come and read the Torah and explain it to the Muslims, he advised them to adopt a neutral stance, neither believing nor disbelieving in it 

"Do not believe the people of the Book, nor disbelieve them, but say, 'We believe in Allah and whatever is revealed to us, and whatever is revealed to you.' " 

This is because the scriptures of the Jews are an amalgam of truth and falsehood, the truthful parts being covered by the statement "whatever is revealed to you". Ibn Abbas would reprimand the Muslims who would seek information from the people of the book in religious matters, on the basis that

 "Allah has told you that the people of the scripture changed their scripture and distorted it, and wrote the scripture with their own hands and said, 'It is from Allah,' to sell it for a little gain. Does not the knowledge which has come to you prevent you from asking them about anything?" 

The Quran, the prophet, the companions therefore all advise caution when approaching the previous scriptures, as they contain both truth, which the prophet confirmed and revered in the aforementioned statements, and falsehood.

The prophet then proceeded with exposing the learned ones by making them read by themselves the truthful part of the Torah which they had been hiding 

"Bring me one who is learned among you. Then a young man was brought. The transmitter then mentioned the rest of the tradition of stoning". 

This hadith depicting the prophet's reverence for the Torah should this be understood in light of other ahadith, as well as the many Quran passages stating that the Torah isnt absolutely corrupt, that despite the manipulations it still contains remnants of truth, hence the Quran being its guardian/muhaymin. The prophet declared his belief not in the entire Torah, but in the specific ruling on the punishment for adultery, and which Ibn Salam, the Jewish convert to Islam instantly recognized as the "divine verse".

It is this corruption in the absolute sense, which some scholars might have been referring to when they said, while commenting on the above report 

"if the Torah was corrupted he would not have placed it on the pillow and he would not have said: I believe in you and in the one who revealed you". 

This is speaking of complete corruption, which is not what the Muslims believe happened to previous scriptures and traditions. 

-those who misinterpret the book after having fully understood it 2:75

-the uneducated/ummiyun, who have no access to the text and therefore only know the distorted lies of the learned ones 2:78

-those who alter the book physically, passing off their modifications as coming from God 2:79. These alterations may be additions and/or subtractions. Al-kitab, the writing/book alludes to a specific text, as the definite article implies, which is subjected to physical corruption. Al kitab is used for the Bible in the same sura. The Quran accuses the Jews of misinterpreting Al kitab while claiming it is from God 3:78 in reference to the HB, just as it exposes the physical corruption of Al kitab 2:79 in reference to the HB. This accusation the Quran makes is the climax of scriptural abuse, fitting into its overall polemic against Jews and Christians. Interestingly, we find similar statements  as regards the integrity of the biblical text among early Christians themselves. Justin Martyr in his dialogue with Trypho the Jew made that exact accusation against the Jewish elite whose responsibility was to preserve the Hebrew Bible.

Ibn Abbas, in comment to the verse said

"O the group of Muslims! How can you ask the people of the Scriptures about anything while your Book which Allah has revealed to your Prophet contains the most recent news from Allah and is pure and not distorted? Allah has told you that the people of the Scriptures have changed some of Allah's Books and distorted it and wrote something with their own hands and said, 'This is from Allah, so as to have a minor gain for it".

However there is another statement attributed to ibn abbas saying 

“No one can corrupt the text by removing any of Allah’s words from his Books, but they corrupted it by misinterpreting it”.  

This is a known defective narration, without any chain of reporters, as noted by the scholars of hadith, including Al Asqalani. What can at most be construed from that statement, assuming it is authentic for argument's sake, is that the incorruptibility is in reference to the heavenly tablet. It can obviously not be speaking of the worldly text which anyone can change. The Quran says all the revealed scriptures are inscribed in umm al kitab/the mother book, inscribed on the heavenly tablet. None can change the words therein but only twist their meaning. Ibn Kathir understood that nuance between the 2 ahadith of ibn Abbas very well. He quotes the weak hadith in his tafsir of 3:78 which speaks of oral misinterpretation. But he also refers to ibn Abbas' authentic comment on 2:79 that speaks of textual corruption by the people of the book. Ibn Kathir quotes other companion views on 2:79, including that of Uthman saying that 

"they (the Jews) distorted the Torah. They added to it what they liked and erased from it what they hated and they erased the name of Muhammad peace be upon him from the Torah and for that Allah became angry". 

Ibn Kathir and the earliest Muslim belief regarding the oral and textual corruption of the Bible is therefore clearly established, based on the Quran itself. That Muslim position is even reflected in the polemical writings of John of Damascus, some 100 years after the prophet's death 

"But some of them say that it is by misinterpretation that we have represented the Prophets as saying such things, while others say that the Hebrews hated us and deceived us by writing in the name of the Prophets so that we might be lost". 

As already noted, anyone can remove and alter words from any worldly text at any point in time. And if that is done when not enough human and textual witnesses can independently detect that corruption, then it can easily be disseminated and passed off as true. That is what happened during the successive destructions of the Israelite nation, followed by the attempts of their scribes to re-write what was lost. Al-Razi rightly noted 

"It is impossible to have a conspiracy to change or alter the word of God in all of these copies without missing any copy. Such a conspiracy will not be logical or possible".  

Al-Razi here is talking of a time when previous scriptures, although in their corrupt state (see his commentary on 5:41), were already widely disseminated and could be independently attested by countless witnesses. Nobody could remove Allah's word nor any other man-made word from it then, without being detected. Corruption of the Torah at that point became only possible through misinterpretation. 

Similarly, some stated that the Torah cannot be corrupted, based on the verse saying God's words cannot be changed 6:115. Again, any worldly copy of the Torah can be altered. But so long as there exists the possibility for the original to be reproduced, God's words remain unaffected, only the copy of these words. 

The Quran is the speech of Allah, and that speech is with Allah, uncreated, eternal, unchanged like any other attribute of His. The analogy of God's speech to the Quran we touch with our hands or recite from our minds, is as God's mercy which manifests in tangible and abstract things. Both types of manifestations are created means through which God's uncreated attributes of speech and mercy are made known to humans. These attributes arent limited to those particular manifestations 

31:27"and If all the trees on the earth were pens, and the sea replenished with seven more seas [were ink], the words of Allah would not be spent". 

God's speech is therefore unexhaustive. It can potentially bring into existence a limitless number of words of revelation, among them the Hebrew Torah of Moses or the Arabic Quran of Muhammad 

14:4"And We did not send any messenger but with the language of his people, so that he might explain to them clearly". 

Allah further states about the revelation to Muhammad, that He 

43:3"made it an Arabic Quran". 

The eternal speech of Allah takes on in this world the form that is relevant to the divine purpose. The Arabic Quran was thus not continuously spoken since eternity. It is the manifestation in time of God's eternal attribute of speech. Just like we may say a healthy newborn is the manifestation in time of God's eternal attribute of mercy.

Assuming for argument's sake that all things in the heavens and the earth are destroyed, including all Torahs and Qurans, the mother of the book that contains all revelations, and even the preserved tablet/lawh mahfuz. So long as the potential to generate a true Quran and Torah exists, then Allah's words that were revealed to Moses and Muhammad remain unaffected. As stated earlier, the physical and abstract things in which God's attributes manifest in this world do not exhaust the attributes themselves, neither do these manifestations share the uncreated essence of the attributes they are representing. This is the problem of Trinitarians. Jesus, a created being, is not merely a manifestation of God's word, rather he incarnates it fully, becoming this divine "person" with contradictory attributes Trinitarian thinkers have been struggling to explain for over 2000 years. Christians are quick to try and parallel the notion of uncreatedness of God's speech as manifested in the Quran, with their idea derived from the Gospel of John where God's uncreated word manifested in Jesus. The two concepts, arent comparable.  Further, why would trinitarians even need the Quran to explain the logical and philosophical problems of their theology.

Not a single group within Islam says the Quran was a separate entity floating around next to God since eternity past. This is how some Christians, with their trinitarian worldview, misrepresent the statement that the word of Allah is uncreated. In Christianity, the word is not an attribute but a divine person among others like the father and holy spirit, each with distinct attributes. One man with multiple attributes isnt many men just as One God with multiple attributes isnt many gods. This is tawhid. Yet Trinity says each person is divine but with different attributes, resulting in 3 different gods. The analogy Christians attempt between tawhid and trinity stops at the word of God being eternal. Christians made that word a person with attributes among other distinct persons, while Muslims kept the word as an attribute among others within the essence of the One God. As an aside, since the word or speech of God is not an attribute within the divine essence but a separate divine entity along with 2 others, does it mean that only this divine entity called "word or speech" has the ability to speak and that the other 2 divine entities are mute?

 If God's word is a separate divine entity that became flesh in Jesus, what about the words uttered by Jesus who is now divine? Are his words separate divine entities? Further, if the Torah is God's word, as Jews and Christians believe, does that make it divine as Jesus is? These are the kinds of problems Trinitarians are entangled with due to their conjectures on ambiguous matters, instead of relying on firm statements on God's oneness and unity. Muslims on the other hand, despite the early disputes as to whether the Quran was created or not, never went out of the way to declare the attributes of God, like His word, separate divine entities. No Muslim ever believed God's speech to be a separate conscious part. The reason why this issue is often brought up by Trinitarians is that the Quran is the only book that claims to be Allah's direct speech. The Bible doesnt make that claim. The closest one finds is an anonymous claim made about Jesus being God's word. Muslims on the other hand stick to clear and firm statements of scriptures to define their cardinal beliefs, including that "nothing is like a likeness of Him".

2:79 is a timeless warning, addressed to any corrupt scribes among the Jews who would in addition reap profit from such an evil deed. It is not specific to the Jews of the time of the prophet. This means, although that type of corruption did occur, it may have happened before or during the prophet's time as well as both. No contemporary 7th century Jewish writing has survived so as to compare with older manuscripts to know whether this was done during the time of the prophet. And even if such 7th century writing is found, agreeing with older manuscripts, then it still does not negate that the corruption might have occured much longer before the prophet's time. Another thing to note is that this verse doesnt target the writings of the Christians. The books that these groups follow are not the singular Gospel of Jesus of which the Quran speaks. As the Quran repeatedly says, they follow but mere conjecture. This conjecture has taken the shape of the Greek writings compiled as the New Testament. They are writings that interpret and re-interpret Jesus' words and singular Gospel, giving them a completely different intent. Sometimes this conjecture doesnt take for basis Jesus' Gospel at all, such as with the notion of human depravity and sin atonement. The Quran thus appropriately tells the Christians to abide by the singular Gospel of Jesus to find the right path that will lead them to the truth of the Quran.

When they did so, in contrast to the corrupt aforementioned groups, when they remained truthful to the scriptures in anyway, shape or form it reached them, trying to follow it to the best of their ability, then their sincerity, unprejudiced reading and understanding of their books led them to inevitably believe in the revelation bestowed on the prophet Muhammad 2:121,83,3:113-115,199,4:162,5:13,66,69,83,7:159-170,17:107-9,28:52-4. This is what occured in the times of the prophet, even among their most learned figures, just as it occured throughout time and in our days. The Quran thus expects the Jews and Christians to recognize the truth based on what is in their hands first and foremost. The prophethood of Muhammad and the truth revealed to him make ample theological sense within their own written and oral traditions.

When they behaved with insincerity, hypocrisy towards their books 2:85, then despite having sources of light and guidance in their hands, it availed them nothing "The Torah and the Gospel are with the Jews and the Christians but what do they avail of them?" (Tirmidhi 2653). They become followers of deliberate corruption and lies, or mislead by conjecture.

Acts17apologetics find consolation; Allah cannot change His word?

In answer to the video "Answering Islam 12: What Does the Quran Say about the Bible?"

Kalimatullah in these contexts is simply the word of God in the sense of His promise as amply used in the Quran 6:34,115,10:64,18:27 etc. Such divine word is a command that can never be reversed or altered once issued 13:41, it can be the promise of victory and assistance to the messengers and their followers 37:171-2 or the promise of chastisement to the rejecters 58:21 or again the promises of miracles or blessings whether in this life or the next. This is because, as repeatedly said in the Book, Allah's statement is truthful and He never breaks His promise

10:55,33:4,38:34"The truth then is and the truth do I speak"  

39:20"Allah will not fail in (His promise)".
