CIRA International tacle old theory; Quran does not say Allah will preserve it?

In answer to the video "The Unknown History of Islam 09 - Racism and the Islamic Slave Trade"

Allah has repeatedly pledged throughout the Quran that He will structure and compile, explain and protect the Quran from falsehood

15:9"Verily, we have sent down the Reminder, and, verily, we will guard it".

This verse comes in answer to the prophet's opponents, trying to discredit him with taunts and sarcasms. It tells them this reminder is divinely sent, meaning not the product of the person they are objecting to. So in reality they are opposing God who sent it. And even if they try to oppose the One who sent it, the only way being to tamper or destroy His communications, then the verse tells them in the form of a strong affirmation, this revelation will remain firmly guarded.

As a side note, "the reminder/al dhikr" is a general word that may be used to anything that serves the function of reminding. This reminding can be done in many ways, including orally. It is the context that defines what is meant by it.

In 15:9 above it means the Quran, whether written or recited from memory. The pledge of protection despite the people's opposition to Muhammad refers only to the Quran in that passage.

In 16:43, the reminder/al dhikr refers to whatever served the function of reminding prior to the Quran, and this includes both written and oral traditions of the Jews and Christians, in totality.

In 21:105 the dhikr still refers to whatever served the function of reminding prior to the Quran, but this time, to the exclusion of certain Judeo-Christian scriptures, namely the Psalms and all that came after it. Dhikr here refers to what was divinely inspired prior to the Psalms of David.

In 40:53-4 the dhikr/the reminder is in reference to what served as a reminder of the truth to the Israelites only, and which they inherited from Moses. This means the Torah exclusively. All these verse prove that the generic word dhikr/reminder is flexible and its application depends on the context of its use; it does not mean the same thing everytime it appears, and not everything that the Quran says about it in a context, applies to another context.

Just as when it refers to both the Quran and the Torah with the general word "writing/kitab" doesnt mean they are one and the same writing, or that what it says in the context of the writing being the Quran, also applies to the Torah because it is also called a writing in another passage. The same goes for other dual applications of general words to both the Quran and previous scriptures, such as criterion, guidance, light etc.

Other pledges of divine protection of the Quran are found in

75:17-19"Surely on Us (devolves) the collecting of it and the reciting of it. Therefore when We have recited it, follow its recitation. Again on Us (devolves) the explaining of it"  

41:42"No falsehood can approach it from before or behind it: It is sent down by One Full of Wisdom, Worthy of all Praise"  

4:82"Will they not then ponder on the Quran, Had it been from other Than God, they would surely have found therein Much discrepancy".

It is only following reflection that one doesnt find contradiction in it, this means that should one study it superficially, he would find faults in it.
