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 [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 [He will resurrect them] to the end that He might make clear unto them all whereon they [now] hold divergent views, and that they who are bent on denying the truth [of resurrection] might come to know that they were liars. 39 Indeed, Our word to a thing when We intend it is but that We say to it, "Be," and it is. 40
