no any letter changed in The Muslims holy book (Qura'an) for about 1400 years:
[112:0] In the name of God, Most Gracious, Most Merciful
[112:1] Proclaim, "He is the One and only GOD.
[112:2] "The Absolute GOD.
[112:3] "Never did He beget. Nor was He begotten. <A name=4>[112:4] "None equals Him."

Sorry but since you brought it up, this is how the Quran appears to me:
a. incomprehensible
b. noncohesive
c. incoherent
Now I am sure there are those who would say the same thing about the Bible. But really in purely literal terms there is no comparison between the two. As a matter of fact it becomes obvious that one borrows heavily from the other, but that's not even the worst of it. Where's the beef? Where's the story? Why would anyone take a bunch of verses and sort them BY LENGTH?? Of COURSE it doesn't "flow". There is no chronology, no heart to it, nothing that to me would place it in the category of readable literature even. It is a mess. It appears contrived.
I came away disappointed, for a reader it's the worst crime any book can commit. For me finally reading the entire Quran was like standing in line to see the emperor's glorious new clothes and then....
This is only MY honest opinion, based on only ONE (interminably boring and frustrating) reading. I promised myself never to put myself through that again.
