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 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 produced [many] generations [after Moses], and prolonged was their duration. And you were not a resident among the people of Madyan, reciting to them Our verses, but We were senders [of this message]. 45 You were not present on the side of Mount Sinai when We called. And all this (knowledge that you are given) is by the grace of your Lord so that you may warn a people to whom no admonisher had come before you, that they may take heed; 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 Yet when the truth is come unto them from before Us, they say: wherefore hast he not been vouchsafed the like of that which was given unto Musa? Disbelieved they not in that which was given unto Musa aforetime? They say; two magics supporting each other. And they say: verily in all such things we are disbelievers. 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 do not answer thee, know that they are only following their caprices; and who is further astray than he who follows his caprice without guidance from God? Surely God guides not the people of the evildoers. 50
