And We gave Moses the Scripture, after We had destroyed the former generations, as enlightenment for the people and guidance and mercy that they might be reminded. 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 We raised generations who lived long. You did not live among the people of Midian, nor did you recite to them Our verses; but We were sending Messengers. 45 Nor wast thou beside the Tur when We called; but thou art sent as a mercy from thy Lord, that thou mayest warn a people unto whom no warner came before thee, that haply they might be admonished. 46 And if not that a disaster should strike them for what their hands put forth [of sins] and they would say, "Our Lord, why did You not send us a messenger so we could have followed Your verses and been among the believers?"... 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 Say: "Then bring a Book from God which gives better guidance than these so that I may follow it, if you speak the truth." 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
