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 upon the western side when We decreed to Moses the commandment, nor wast thou of those witnessing; 44 but We raised up generations, and long their lives continued. Neither wast thou a dweller among the Midianites, reciting to them Our signs; but We were sending Messengers. 45 And nor were you beside the Mount when We proclaimed – however it is a mercy from your Lord* so that you may warn a nation towards whom no Herald of Warning came before you, in the hope of their heeding advice. (*That He has bestowed knowledge of the hidden to you) 46 Otherwise, if disaster should afflict them because of that which their own hands have sent before (them), they might say: Our Lord! Why sentest Thou no messenger unto us, that we might have followed Thy revelations and been of the believers? 47 And yet, now that the truth has come unto them from Us, they say: "Why has he not been vouchsafed the like of what Moses was vouchsafed?" But did they not also, before this, deny the truth of what Moses was vouchsafed? [For] they do say: "Two examples of delusion, [seemingly] supporting each other!" And they add, "Behold, we refuse to accept either of them as true!" 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 If they cannot meet such a challenge, know that they are only following their (evil) desires. Who strays more than one who follows his desires without guidance from God? God does not guide the unjust people. 50
