That's a good question. Perhaps it does or perhaps it doesn't but, apparently, the message is different.When you read it out aloud, does the oldest Quran sound any different?
Would you like me to look up the reference?
I beleive it suggests there are thousands of small differences.
Would it matter?
Would it make your Qur'an any different if tomorrow Muslim scholars unearthed the oldest Qur'an in existence and it had many difference and perhaps a few extra chapters?
It seems to me one can not be better than Perfect?
