You know, if the qu'ran is as unchanging as muslims say and as clearly defined in origin as the author alleges, why don't muslim authorities allow anybody but a select few, extremely doctrinaire, imams to view and study the oldest versions of the book. The earliest available to general scholarship are from the mid ninth century whereas we know of versions from the end of the seventh.

That would suggest that the qu'ran was heavily revised over 150 years.
