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 (Muhammad), you were not present at the west bank to witness when We gave the commandments to Moses. 44 But We raised up generations, then life became prolonged to them; and you were not dwelling among the people of Madyan, reciting to them Our communications, but We were the senders. 45 And you were not at the side of the mount when We called [Moses] but [were sent] as a mercy from your Lord to warn a people to whom no warner had come before you that they might be reminded. 46 If (We had) not (sent thee to the Quraish),- in case a calamity should seize them for (the deeds) that their hands have sent forth, they might say: "Our Lord! why didst Thou not sent us a messenger? We should then have followed Thy Signs and been amongst those who believe!" 47 But (now), when the Truth has come to them from Ourselves, they say, "Why are not (Signs) sent to him, like those which were sent to Moses?" Do they not then reject (the Signs) which were formerly sent to Moses? They say: "Two kinds of sorcery, each assisting the other!" And they say: "For us, we reject all (such things)!" 48 Say thou: then bring a Book from before Allah, that is better in guidance than these two, I shall follow it - if ye are truth-tellers. 49 Then if they answer thee not, know thou that they only follow their own desires; and who is farther astray than he who followeth his desire without guidance from Allah? Verily Allah guideth not a wrong-doing people. 50
