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 [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 strongly swear by God that God will not bring the dead to life. God's promise (of the Resurrection) will certainly come true but many people do not know. 38 So that He might make manifest to them that about which they differ, and that those who disbelieve might know that they were liars. 39 And Our word unto a thing, when We intend it, is only that We say unto it: Be! and it is. 40
