After We had destroyed the earlier generations, We gave Moses the Book to give men insight, and as guidance and a blessing for people, so that they might take heed. 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 But We brought forth generations, and prolonged unto them was life; nor wast thou a dweller among the people of Madyan, reciting unto them Our revelations; but it is We who were to send. 45 Nor were you on the side of the Mount (Sinai) when We called out to Moses (in the first instance). But it is out of Mercy from your Lord (that you are being informed of all this) so that you may warn a people to whom no warner came before you. Maybe they will take heed. 46 and [We have sent thee] lest they say [on Judgment Day,] when disaster befalls them as an outcome of what their own hands have wrought, "O our Sustainer, if only Thou had sent an apostle unto us, we would have followed Thy messages, and would have been among those who believe!" 47 But when the truth came to them from Us, they said: "Why is he not given the like of what was given to Moses?" Did they not disbelieve before in what was given to Moses? They said: "Both are imposters one like the other," and added: "We do not believe in either." 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 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
