And those who associate others with Allah say, "If Allah had willed, we would not have worshipped anything other than Him, neither we nor our fathers, nor would we have forbidden anything through other than Him." Thus did those do before them. So is there upon the messengers except [the duty of] clear notification? 35 And indeed We sent to every nation a Noble Messenger (proclaiming) that “Worship Allah and beware of the devil”; therefore Allah guided some of them, and error proved true upon some of them; therefore travel in the land and see what sort of fate befell the deniers! 36 If thou art anxious for their guidance, yet Allah guideth not such as He leaves to stray, and there is none 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 In order that He may make clear to them the matter in which they differed, and the disbelievers may realise that they were liars. 39 When We will something to happen, all that We say is, "Be!" and it is. 40
