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 assuredly We have raised in every community an apostle saying: worship Allah and avoid the devil. Then of them were some whom Allah guided, and of them were some upon whom the straying was justified. Wherefore travel about on the earth, and look on what wise hath been the end of the disbelievers. 36 Even if thou (O Muhammad) desirest their right guidance, still Allah assuredly will not guide him who misleadeth. Such have no 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 For (they fear) He might make what they differed about plain to them, and that the infidels may realise that they were liars. 39 For to anything which We have willed, We but say the word, "Be", and it is. 40
