Those who associate others with Allah in His Divinity say: "Were Allah to will so, neither we nor our forefathers would have worshipped any other than Him, nor would we have prohibited anything without His command." Their predecessors proffered similar excuses. Do the Messengers have any other duty but to plainly convey the 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 Though thou art ever so eager to guide them, God guides not those whom He leads astray; they have 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 When We decree a thing, We only say: 'Be' and it is. 40
