And the polytheists said, “Had Allah willed, we would not have worshipped anything besides Him – neither we nor our forefathers – and nor would we have forbidden anything, whilst being disassociated with Him”; those before them did exactly this; so what is (incumbent) upon the Noble Messengers, except to plainly convey (the 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 They swear most solemnly in the name of Allah and say: "Allah shall not raise to life any who dies." (Yes, He will do so); that is a promise by which He is bound, even though most people do not know that. 38 In order that He may make clear to them the matter in which they differed, and the disbelievers may realise that they were liars. 39 When We will something to happen, all that We say is, "Be!" and it is. 40
