And We gave Moses the Book, after We had destroyed the former generations, to be reflections for people and a guidance, and a mercy in order that they might remember. 43 NOW [as for thee, O Muhammad,] thou wert not present on the sunset slope [of Mount Sinai] when We imposed the Law upon Moses, nor wert thou among those who witnessed [his times]: 44 We raised (many more) generations and prolonged their lives. You did not live with the people of Midian, nor recited to them Our revelations; but We kept on sending messengers. 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 And if (We had) not (sent you to the people of Makkah) in case a calamity should seize them for (the deeds) that their hands have sent forth, they should have said: "Our Lord! Why did You not send us a Messenger? We should then have followed Your Ayat (Verses of the Quran) and should have been among the believers." 47 When the Truth from Us came to them they said, "Would that he, (Muhammad), had received what was given to Moses (by his Lord)." Did not they reject what Moses had brought to them saying, "These two, Moses and Aaron, are two magicians who support each other. We do not have any faith in them." 48 Say: "Produce, then, [another] revelation from God which would offer better guidance than either of these two [and] I shall follow it, if you speak the truth!" 49 If they cannot meet such a challenge, know that they are only following their (evil) desires. Who strays more than one who follows his desires without guidance from God? God does not guide the unjust people. 50
