Apostate prophet searches for the common pattern; is it the same God through different laws?

In answer to the video "Top 5 Misconceptions About Islam - Debunked (Merciful Servant)"

It is important to note here that the core tenets of religion have always remained unchanged and shall remain so; however, as far as the rituals and customs are concerned, God has prescribed them separately and differently in the course of human history. They are trials to determine who turns away from the truth by showing bias and prejudice to these rituals and customs and who becomes the real seeker of the truth and accepts them in every form that they come to them from God and His prophets. This is precisely why the Quran often states that the people, regardless of their chosen spiritual ways will be judged according to their faithfulness in abiding by these core tenets

22:17,5:48"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".

That 16:101 is speaking of the previous scriptures can also be inferred from 16:103 where the person pointed to as the probable secret teacher of the prophet was suspected of teaching him the stories of the Bible as reported in the traditions.

It would be appropriate here to further elaborate on 3:93, which addresses the issue of negation of abrogation by the Jews. The Torah is in fact an example of abrogation in and of itself, forbidding certain foods that were allowed before, placing restrictions in situations where there were none. The verse states that among the Israelite prophets that preceded Moses and the Torah, only Jacob/Israel had forbidden to himself certain foods.

Tradition tells us it was the choicest of meats for an Egyptian, that of camels, as a testimony of his gratitude to God for having healed his sickness. It could also be referring to other kinds of food for health or personal taste reasons. Although it wasnt requested from them, the Israelites, who wanted to emulate the prophet Jacob kept on forbidding themselves these foods. But every other food was allowed to them, including the very ones Jacob had disallowed for himself, before the revelation of the Torah.

When Revelation later came to Moses, God abrogated this principle. Certain foods were forbidden, either as a burden placed on them specifically because of their sins as already stated above, or as an everlasting ordinance, as in the case of pork meat for instance 6:146. This reality strikes at the heart of a matter which the followers of previous scriptures, more specifically the Jews during the advent of Islam and even up to this day, could not admit; the issue of abrogation of a previous divine system by the very One who first decreed it. That is why they are then told to bring the scriptural proof for their claim that the dietary requirements of the Mosaic law preceded the Torah, and since they obviously couldnt, then it means God did in fact, through the Torah, abolish a previous system He had validated for them and their forefather Abraham whose way was now being restored in front of their eyes

3:93-5"All food was lawful to the children of Israel except that which Israel had forbidden to himself, before the Taurat was revealed. Say: Bring then the Taurat and read it, if you are truthful. Then whoever fabricates a lie against Allah after this, these it is that are the unjust. Say: Allah has spoken the truth, therefore follow the religion of Ibrahim, the upright one; and he was not one of the polytheists".

This is part of a wider passage similarly admonishing the Jews for their blind dogmatism and stubborn denial of various aspects of the truth, despite the clear arguments and signs presented to them.

In 2:106 the Quran adresses the followers of previous scriptures, summing up this principle of superseding divine revelations, making it clear to them that

13:38"For every term there is a book"  

5:48"for every one of you did We appoint a law and a way"  

22:67"therefore they should not dispute with you about the matter and call to your Lord; most surely you are on a right way"

and that

13:39"Allah makes to pass away and establishes what He pleases"

and all is done according to established heavenly and unchanging principles present with God

"and with Him is the basis of the Book"

Who did not create the universe but

46:3"with truth and (for) an appointed term". 

2:106 comes in a context where they are being admonished for their history of carelesness towards their revealed Books and their refusal to accept a new revelation. Their refusal being primarily rooted in it being bestowed on someone outside of their fold. It tells them the Quran has now superseded the previous revelations by abrogating them in part through the modification of previous laws that were either meant as a punishement for their transgressions, or were more applicable for the age. In the words of the Quran "better", and as for those that were just as applicable for the age, but forgotten by the People of the Book, God introduced something similar, or in the words of the Quran, "or the like thereof".

The act of forgetfulness is attributed to God in the same way is the "sealing of the hearts". God has allowed it to happen as a result of the carelessness of the People of the Book who besides their going astray into the ways of polytheism as attested in their scriptures, had grown so indifferent to the Torah that we read various incidents in their history and recorded in their books that attest to them having lost knowledge not only of the contents of their books, but also of their whereabouts. This is not to speak even of the complete erasure of their memory of the location of the mountain where they had collectively witnessed the most extraordinary miracles and were collectively made to live the prophetic experience.

What this means is that one is not losing anything from following the new revelation of God, contrary to the mindless ranting of the People of the Book. In fact, God has granted something better and revived what has been forgotten through the Quran.
