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 verily We have raised in every nation a messenger, (proclaiming): Serve Allah and shun false gods. Then some of them (there were) whom Allah guided, and some of them (there were) upon whom error had just hold. Do but travel in the land and see the nature of the consequence for the deniers! 36 Though thou art ever so eager to guide them, God guides not those whom He leads astray; they have no helpers. 37 They swear most solemnly in the name of Allah and say: "Allah shall not raise to life any who dies." (Yes, He will do so); that is a promise by which He is bound, even though most people do not know that. 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 For to anything which We have willed, We but say the word, "Be", and it is. 40
