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 To every nation We sent a Messenger who told its people, "Worship God and stay away from satan." Some of them were guided by God and others were doomed to go astray. Travel through the land and see how terrible was the end for those who rejected the truth! 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 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 This will be in order that he may manifest unto them that wherein they differ, and that those who disbelieved should come to know that they had been liars. 39 Yet when We will a thing We have only to say: "Be", and it is. 40
