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 indeed We sent to every nation a Noble Messenger (proclaiming) that “Worship Allah and beware of the devil”; therefore Allah guided some of them, and error proved true upon some of them; therefore travel in the land and see what sort of fate befell the deniers! 36 Though thou art ever so eager to guide them, God guides not those whom He leads astray; they have no helpers. 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 That He may explain unto them that wherein they differ, and that those who disbelieved 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
