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 [As for those who are bent on denying the truth - ] though thou be ever so eager to show them the right way, [know that,] verily, God does not bestow His guidance upon any whom He judges to have gone astray; and such shall have none to succour them [on Resurrection Day]. 37 And they swear by Allah with the most energetic of their oaths: Allah will not raise up him who dies. Yea! it is a promise binding on Him, quite true, but most people do not know; 38 (That is bound to happen in order that) He may make clear to them the reality regarding the matters on which they differ and that the unbelievers may realize that they were liars. 39 Yet when We will a thing We have only to say: "Be", and it is. 40
