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 (O Muhammad), you were then not on the western side when We bestowed this commandment (of Law), and you were not among its witnesses. 44 But We raised up (new) generations, and long were the ages that passed over them; but thou wast not a dweller among the people of Madyan, rehearsing Our Signs to them; but it is We Who send messengers (with inspiration). 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 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 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: Then bring some (other) book from Allah which is a better guide than both of them, (that) I may follow it, if you are truthful. 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
