And We indeed gave Moosa the Book after We had destroyed the former generations, having enlightenment for mankind, and a guidance and a mercy, for them to accept advice. 43 And thou (Muhammad) wast not on the western side (of the Mount) when We expounded unto Moses the commandment, and thou wast not among those present; 44 But We raised many generations after Moses and they lived for many years. You did not dwell with the people of Midian reciting Our revelations to them, but We had certainly sent Messengers to them. 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 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 But (now) when the truth has come to them from Us, they say: Why is he not given the like of what was given to Musa? What! did they not disbelieve in what Musa was given before? They say: Two magicians backing up each other; and they say: Surely we are unbelievers in all. 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 do not answer you, know that they are only following their desires. And who is further astray than he who is led by his desires without guidance from Allah! Allah does not guide the harmdoers. 50
