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 They have sworn by God the most earnest oaths God will never raise up him who dies; nay, it is a promise binding upon Him, but most men know not, 38 This is in order that He may make clear to them that which they differed upon, and in order that those who disbelieve might know that they were indeed lying. 39 And Our command for anything to occur, when We will it, is that We only say to it, “Be” – and it thereupon happens. 40
