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 (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 We raised generations who lived long. You did not live among the people of Midian, nor did you recite to them Our verses; but We were sending Messengers. 45 You had not been present at the side of the Mount (Sinai) when We called Moses (from the tree), but through Our mercy we told you his story so that you might warn the people 46 And lest, if an affliction had afflicted them for that which their hands had sent before, they should have said: our Lord! wherefore sent not Thou an apostle unto us that we might have followed Thy revelations and been of the 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 Say: 'Bring a Book from God that gives better guidance than these, and follow it, if you speak truly.' 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
