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 And you (O dear Prophet Mohammed – peace and blessings be upon him) were not on the western side of the Mount when We sent the command of Prophethood to Moosa, and you were not present. (Yet you narrate the account very clearly to the Jews and Christians.) 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 And neither wert thou present on the slope of Mount Sinai when We called out [to Moses]: but [thou, too, art sent] as an act of thy Sustainer's grace, to warn people to whom no warner has come before thee, so that they might bethink themselves [of Us]; 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 But when the truth came to them from Us, they said: "Why is he not given the like of what was given to Moses?" Did they not disbelieve before in what was given to Moses? They said: "Both are imposters one like the other," and added: "We do not believe in either." 48 Say: 'If what you say is true, bring down from Allah a Book that is a better guidance than both, I will follow it' 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
