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 You were not there on the western side (of Mount Sinai) when We gave the commandments to Moses, nor were you witness (to the event). 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 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 to whom no warner had been sent that perhaps they might take heed, and that, on experiencing afflictions because of their own deeds, they may not say, "Lord, would that You had sent to us a Messenger so that we could follow Your revelations and become believers". 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: "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 But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people. 50
