Muslims are allowed to kill, steal or commit adultery, as long as they do not worship others besides Allah!

This so called "Prophet" Muhammad said: “Gabriel said to me: Whoever amongst your followers die without having worshipped others besides Allah, will enter Paradise; I said: Even if he has committed illegal sexual intercourse or theft?  He replied, “Even if he has committed illegal sexual intercourse or theft”!!
