That's the Koran.
Concerning the Hypocrites who distort the words of the Prophet the Koran provides for death in their case too.

Obviously some people get away with Hypocrisy and found new Islamic sects. They and their followers have to watch out forever after because members of other sects may kill them.

Many Moslems place more faith in Sharia than the Hadiths or the Koran.
