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 Even if thou (O Muhammad) desirest their right guidance, still Allah assuredly will not guide him who misleadeth. Such have no helpers. 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 For to anything which We have willed, We but say the word, "Be", and it is. 40
