Quran 6.32-34
Naught is the life of the world save a pastime and a spot. Better far is the abode of the Hereafter for those who keep their duty (to Allah). Have ye then no sense? We know well how their talk grieveth thee, though in truth they deny not thee (Muhammad) but evil-doers flout the revelations of Allah. Messengers indeed have been denied before thee, and they were patient under the denial and the persecution till Our succour reached them. There is none to alter the decisions of Allah. Already there hath reached thee (somewhat) of the tidings of the messengers (We sent before).
