Those who associate [others with God] say, "If God had so willed we would not have worshipped anything besides Him, neither we nor our fathers, nor would we have forbidden anything without His sanction." So did those who went before them. The duty of the messengers is only to convey the message clearly. 35 We sent a Messenger to every nation, saying: 'Worship Allah and avoid the idols' Amongst them were some whom Allah guided, and some justly disposed to error. Travel in the land and see what was the end of those who belied (the Revelation and the prophets)! 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 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 (As for the possibility of resurrection, bear in mind that) whenever We do will something, We have to do no more than say: "Be", and it is. 40
