The idolators say, 'If God had willed we would not have served; apart from Him, anything, neither we nor our fathers, nor would we have forbidden, apart from Him, anything.' So did those before them; yet is aught for the Messengers, but to deliver the manifest Message? 35 And We certainly sent into every nation a messenger, [saying], "Worship Allah and avoid Taghut." And among them were those whom Allah guided, and among them were those upon whom error was [deservedly] decreed. So proceed through the earth and observe how was the end of the deniers. 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 And they swore by Allah most vehemently in their oaths that, “Allah will not raise up the dead”; yes He will, why not? A true promise obligatory upon Him, but most men do not know. 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 Yet when We will a thing We have only to say: "Be", and it is. 40
