After We had destroyed the earlier generations, We gave Moses the Book to give men insight, and as guidance and a blessing for people, so that they might take heed. 43 You were not present on the western side of the Mount when We gave Our Command to Moses: nor were you among the witnesses, 44 but We raised up generations, and long their lives continued. Neither wast thou a dweller among the Midianites, reciting to them Our signs; but We were sending Messengers. 45 Thou wast not upon the side of the Mount when We called; but for a mercy from thy Lord, that thou mayest warn a people to whom no warner came before thee, and that haply they may remember. 46 Otherwise, if some disaster befell them because of what their own hands have sent forward they would say, “Our Lord! Why did you not send a Noble Messenger towards us, so we may have followed Your signs and accepted faith?” 47 So when the truth (Prophet Muhammad) came to them from Us, they said: 'Why is he not given the like of that which was given to Moses' But did they not also disbelieve in that which Moses was given before! They say (about Moses and Aaron): 'Two sorcerers supporting one another' And they said: 'We disbelieve both' 48 Tell them, (O Prophet): "Then do bring a Book from Allah which is a better guide than either of them, and I will follow it! Do so if you are truthful!" 49 And since they cannot respond to this thy challenge, know that they are following only their own likes and dislikes: and who could be more astray than he who follows [but] his own likes and dislikes without any guidance from God? Verily, God does not grace with His guidance people who are given to evildoing! 50
