The idolaters say: 'Had Allah willed, neither we nor our fathers would have worshipped anything other than Him, nor would we have forbidden anything without Him', as such did those before them. Yet what should Messengers do but give a clear deliverance? 35 And certainly We raised in every nation an apostle saying: Serve Allah and shun the Shaitan. So there were some of them whom Allah guided and there were others against whom error was due; therefore travel in the land, then see what was the end of the rejecters. 36 [Even] if you should strive for their guidance, [O Muhammad], indeed, Allah does not guide those He sends astray, and they will have no helpers. 37 They swear their strongest oaths by God that God will never raise the dead to life -- nonetheless, it is a promise truly binding on Him, even though most people do not realize it -- 38 [It is] so He will make clear to them [the truth of] that wherein they differ and so those who have disbelieved may know that they were liars. 39 Whenever We will anything to be, We but say unto it Our word "Be" - and it is. 40
