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 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 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 (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 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 If they do not respond to you, then know that they follow only their own desires. Who could be more astray than he who follows his own likes and dislikes with no guidance from God? God does not guide the evil-doers. 50
