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 [As for those who are bent on denying the truth - ] though thou be ever so eager to show them the right way, [know that,] verily, God does not bestow His guidance upon any whom He judges to have gone astray; and such shall have none to succour them [on Resurrection Day]. 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 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
