We did reveal to Moses the Book after We had destroyed the earlier generations, (to give) Insight to men, and guidance and Mercy, that they might receive admonition. 43 (Muhammad), you were not present at the west bank to witness when We gave the commandments to Moses. 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 were not on the side of the Mount when We called out to Moses, but We have sent you as a mercy from your Lord, so that you may warn people to whom no warner has been sent before you, so that they may take heed, 46 and may not say, if an affliction should befall them on account of their misdeeds: "Lord, if only You had sent us a messenger, we might have followed Your message 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 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
