Manuscript Changes in the Quran

I remember around twenty years or so ago, Muslims often claimed that the Quran has been perfectly preserved from when it was first revealed until now.  Back then I had no response to this.
How things have changed!
Recent work by scholars is showing that the Muslims' claim is is no longer defensible.

In the following debate Jay Smith makes very broad and damaging claims about the text of the Quran being corrupt, but Shabir Ally does not defend against them except in small ways.  Shabbir Ally is certainly knowledgeable on this topic--he had defended that the Quran is unchanged in previous debates.
But meanwhile it seems that enough research is available to demonstrate that there are serious problems with the transmission of the Quran, and I expect we will see more of this in the future.

Here is the Jay Smith vs Shabir Ally 2014 debate: (must watch!)

In this debate Jay Smith establishes Manuscript changes, Shabir Ally has no response.

This is the beginning of the end for the claim that the Quran is unchanged.

Here is an entire debate on the historical basis of the Quran.  Note how the Muslim debaters are rarely on topic:

In this video Jay Smith shows the Muslims have severe difficulties with the transmission of the Quran and certainly do not have an original Quran, as they often claim:

Examining the Newest Historical Research on Islam and the Earliest Quranic Manuscripts (Jay Smith)
https://youtu.be/fMJRsd8SrhU
Difficult historical questions for Islam.

Here is a series of five simple videos that Jay Smith has made  that show the history of Quran manuscripts and changes:


1. Is the Qur'an Eternal, Sent down, Complete and Unchanged?

2. Muslim scholars look at the manuscripts
https://youtu.be/D5CQ5jQvlBw

3. Muslim scholars assess the earliest manuscripts

4. Evaluating the Corrections in the manuscripts
https://youtu.be/KckGHArKC3I

5. CONCLUSION: The Qur'an is NOT eternal, NOT sent down, NOT complete NOR unchanged
https://youtu.be/iThVOVT0oJ4

This video shows Jay Smith at Speakers' corner, his favorite setting.
He raises questions like this:
What is your earliest complete manuscript?
What manuscript(s) is your current 1924 Cairo edition based on?  This is the most commonly used Quran today.
Why do the Birmingham manuscripts contain material that pre-dates the Quran we have today?
Why does the Quran borrow from older sources?

Here Jay Smith debates a Muslim at Speaker's corner, but the Muslim quickly drops out and Jay Smith continues the discussion with one of his students:

For now, all you have to know to show Islam is false is a six-word question:

      "Where is your earliest complete manuscript?"
If Islam can't produce a response to this, then that could be the start of the end of Islam.

In contrast, in Christianity, we can easily investigate the manuscript evidence for any word in the New Testament using this software:

There are probably other programs that do this also.
