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 If thou art anxious for their guidance, yet Allah guideth not such as He leaves to stray, and there is none to help them. 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 this is so that He may make clear to them what they have differed about and so that those who are bent on denying the truth may realize that they were lying. 39 When We want to bring something into existence, Our command is, "Exist," and it comes into existence. 40
