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 Indeed, We sent forth among every nation a Messenger saying: 'Serve you God, and eschew idols.' Then some of them God guided, and some were justly disposed to error. So journey in the land, and behold how was the end of them that cried lies. 36 If thou art solicitous for their guidance, then verily Allah guideth not whomsoever He sendeth astray, and for them there are no helpers. 37 And they swear by Allah their strongest oaths [that] Allah will not resurrect one who dies. But yes - [it is] a true promise [binding] upon Him, but most of the people do not know. 38 This is in order that He may make clear to them that which they differed upon, and in order that those who disbelieve might know that they were indeed lying. 39 The only words We say to a thing, when We desire it, is that We say to it 'Be,' and it is. 40
