After We had destroyed the earlier generations We gave Moses the Book as evidence for mankind, and a guidance and grace, so that they may remember. 43 Thou wast not on the Western side when We decreed the Commission to Moses, nor wast thou a witness (of those events). 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 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 (We did so) lest a calamity might seize them because of the misdeeds they committed whereafter they would say: "Our Lord, why did you not send a Messenger to us that we follow Your revelation and become among those who believe?" 47 But when the Truth reached them from Us, they said: "Why was he not given that which was given to Moses?" But did they not reject before what had been given to Moses? They said: "Both are magic, each supporting the other!" And they said: "We deny each of these." 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 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
