What I found interesting is that he is making a point which many may not understand— because the Christians to NOT have a unified book which ALL agree upon,, there is no way that they can rewrite from memory if all the bibles were thrown away. But because there is only ONE version of ARABIC Quran, and thousands have memorized from the first letter to the last, they would be able to rewrite it and have others check and verify its correctness. This procedure actually still occurs when a new print is made: the raw print is read by scholars to check for typing mistakes, deletions, or additions. Only once it has been verified can the press go ahead and make the final print out.
The Uniqueness of the Holy Quran: It is a Single Unified Version!
