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 If thou art anxious for their guidance, yet Allah guideth not such as He leaves to stray, and there is none to help them. 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 In order that He may make manifest to them the truth of that wherein they differ, and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars. 39 When We want to bring something into existence, Our command is, "Exist," and it comes into existence. 40
