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 We brought into being many generations who lived long lives, nor did you live among the people of Midian and recite our revelations to them, it is We who send messengers, 45 You were not present on the side of Mount Sinai when We called. And all this (knowledge that you are given) is by the grace of your Lord so that you may warn a people to whom no admonisher had come before you, that they may take heed; 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 So when the truth (Prophet Muhammad) came to them from Us, they said: 'Why is he not given the like of that which was given to Moses' But did they not also disbelieve in that which Moses was given before! They say (about Moses and Aaron): 'Two sorcerers supporting one another' And they said: 'We disbelieve both' 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 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
