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 (O Muhammad), howsoever eager you may be to show them the Right Way, Allah does not bestow His guidance on those whom He lets go astray; and in fact none will be able to help them. 37 They swear emphatically in the name of God that God will not raise the dead. On the contrary, it is a promise incumbent on Him, though most men do not understand, 38 so that He may make clear to them that whereon they were at variance, and that the unbelievers may know that they were truly liars. 39 Our word for a thing when We intend it, is only that We say to it, Be, and it is. 40
