Those who associate [others with God] say, "If God had so willed we would not have worshipped anything besides Him, neither we nor our fathers, nor would we have forbidden anything without His sanction." So did those who went before them. The duty of the messengers is only to convey the message clearly. 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 [As for those who are bent on denying the truth - ] though thou be ever so eager to show them the right way, [know that,] verily, God does not bestow His guidance upon any whom He judges to have gone astray; and such shall have none to succour them [on Resurrection Day]. 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 this is so that He may make clear to them what they have differed about and so that those who are bent on denying the truth may realize that they were lying. 39 When We want to bring something into existence, Our command is, "Exist," and it comes into existence. 40
