He decided that the Arabs needed one god to worship, because they were worshipping about 100,00 different gods at the time. From the plethora of idols worshipped, he chose Allah, the moon-god.
The koran was not compiled by him, but by his followers. Whenever he would speak, a stenographer would record his speaches and the transcripts would be saved in a basket...the older speaches on the bottom. Later, it was decided to complie all of the transcripts into one text. Since the most recent writings were on top, they were recorded first, all the way to the oldest. Today, when reading the koran, the oldest of his sayings are at the back and the newest, at the front. You'll notice that the newest are the most vicious and restrictive, because as his following grew, so did his rejection and hence, we see his anger against those that don't hold his views.
He is as he was. A heretic.
oops...how insensitive of me.
baa
Moon-god. Sheesh. And I thought the Mormans had it rough.
