Isn't it interesting that Islam really is a reflection of Muhammad..not so much so their god Allah?
As a side note, I'm not so sure that Muhammad was illiterate...I realize that is the muslim claim, but consider, this is a guy who for years handled the business dealings for a very rich widow. The most literate group of people in that era were the businessmen (and in cultures with written scriptures the priest class was also among the most literate). So it seems very unlikely that Muhammad was illiterate and still successful in managing the wife's business holdings.
I've often wondered about the 'illiterate' part, too. He probably wasn't; but he likely was unable to write for some while after his siezures.
It was definitely the "companions" who wrote down the Koranus verses, either from dictation, or by listening to his mumblings during the attacks.
Excellent observation!!
