And We indeed gave Moosa the Book after We had destroyed the former generations, having enlightenment for mankind, and a guidance and a mercy, for them to accept advice. 43 And thou (Muhammad) wast not on the western side (of the Mount) when We expounded unto Moses the commandment, and thou wast not among those present; 44 We brought into being many generations who lived long lives, nor did you live among the people of Midian and recite our revelations to them, it is We who send 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 And yet, now that the truth has come unto them from Us, they say: "Why has he not been vouchsafed the like of what Moses was vouchsafed?" But did they not also, before this, deny the truth of what Moses was vouchsafed? [For] they do say: "Two examples of delusion, [seemingly] supporting each other!" And they add, "Behold, we refuse to accept either of them as true!" 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 Then if they do not answer thee, know that they are only following their caprices; and who is further astray than he who follows his caprice without guidance from God? Surely God guides not the people of the evildoers. 50
