The idolators say, 'If God had willed we would not have served; apart from Him, anything, neither we nor our fathers, nor would we have forbidden, apart from Him, anything.' So did those before them; yet is aught for the Messengers, but to deliver the manifest Message? 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 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 Whenever We will anything to be, We but say unto it Our word "Be" - and it is. 40
