After destroying the people of the ancient towns We gave the Book to Moses to be a source of knowledge, a guidance, and mercy for mankind so that perhaps they would take heed. 43 (Prophet Muhammad) you were not on the western side (of the mountain) when We decreed the commandment to Moses, nor were you among those witnessing. 44 But We brought forth generations, and their lives dragged on for them. And thou wast not a dweller in Midian, reciting unto them Our revelations, but We kept sending (messengers to men). 45 You were not present on the side of the Tor when We called. Yet as a mercy from your Lord to warn a nation to whom no warner has been sent before, in order that they 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 Yet when the truth came to them 'from Ourselves, they said, 'Why has he not been given the like' of that Moses was given?' But they, did they not disbelieve also in what Moses was given aforetime? They said, 'A pair of sorceries mutually supporting each other.' They said, 'We disbelieve both.' 48 Say: Then bring some (other) book from Allah which is a better guide than both of them, (that) I may follow it, 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
