22 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him].
23 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah , if you should be truthful.
24 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.

What message is being sent when it says that stones are prepared for disbelievers? It basically says, if your god is real, then your god will protect you from being stoned. I also like how this scripture reeks of arrogance. The Quran is full of gamesmanship and has a very condescending way of talking about other religions.
