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 And certainly We raised in every nation an apostle saying: Serve Allah and shun the Shaitan. So there were some of them whom Allah guided and there were others against whom error was due; therefore travel in the land, then see what was the end of the rejecters. 36 (Muhammad), even though you have a strong desire to guide them, be sure that God will not guide those who have gone astray and no one will be able to help them. 37 And they swear by God the most solemn of oaths that God would not raise him who dieth. Yea! it is a promise on Him incumbent but most of mankind know not. 38 (They must be raised up), in order that He may manifest to them the truth of that wherein they differ, and that the rejecters of Truth may realise that they had indeed (surrendered to) Falsehood. 39 Indeed, Our word to a thing when We intend it is but that We say to it, "Be," and it is. 40
