The idolaters say: "If God had willed we would not have worshipped anything apart from Him, nor would our fathers have done, nor would we have forbidden any thing without His (leave)." So had the people done before them. Therefore it is binding on the prophets to convey the message in clearest terms. 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 Even if thou (O Muhammad) desirest their right guidance, still Allah assuredly will not guide him who misleadeth. Such have no helpers. 37 They swear their strongest oaths by Allah, that Allah will not raise up those who die: Nay, but it is a promise (binding) on Him in truth: but most among mankind realise it not. 38 In order that He may make clear to them the matter in which they differed, and the disbelievers may realise that they were liars. 39 When We will something to happen, all that We say is, "Be!" and it is. 40
