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 If you desire for their guidance, yet surely Allah does not guide him who leads astray, nor shall they have any helpers. 37 And they swear by Allah their strongest oaths, that Allah will not raise up him who dies. Yes, (He will raise them up), a promise (binding) upon Him in truth, but most of mankind know not. 38 so that He may make clear to them that whereon they were at variance, and that the unbelievers may know that they were truly liars. 39 Indeed, Our word to a thing when We intend it is but that We say to it, "Be," and it is. 40
