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 you [Prophet] may be eager to guide them, God does not guide those whom He lets go astray, [because of their refusal to give a positive response to the truth]. They will have no supporters. 37 And they swear by Allah their most binding oaths (that) Allah will not raise up him who dieth. Nay, but it is a promise (binding) upon Him in truth, but most of mankind know not, 38 (They must be raised up), in order that He may manifest to them the truth of that wherein they differ, and that the rejecters of Truth may realise that they had indeed (surrendered to) Falsehood. 39 And Our word unto a thing, when We intend it, is only that We say unto it: Be! and it is. 40
