Since the biographies of mohammad were written a hundred years after he was dead means those stories about him reciting the koran to others is probably false.<quoted text>
The Christian Bible is the only book that has versions.
It is true that Muhammad did not write anything but he had men to write for him and he recited out,
In the case of Jesus, there was nobody to write down anything. Poor man had no scribe as all his disciples were ignorant fools.
After he had disappeared from the scene and was long gone, people wrote ridiculous and absurd tales about him.
Taht is the difference.
There were MANY versions of the koran before someone rewrote it and burnt all the other versions. There is no proof the koran you use now is the same one mohammad supposedly recited.
Don't forget about the satanic verses being removed from the koran.
