And We gave Moses the Book, after that We had destroyed the former generations, to be examples and a guidance and a mercy, that haply so they might remember. 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 up generations, and long their lives continued. Neither wast thou a dweller among the Midianites, reciting to them Our signs; but We were sending Messengers. 45 And thou was not beside the Mount when We did call; but (the knowledge of it is) a mercy from thy Lord that thou mayst warn a folk unto whom no warner came before thee, that haply they may give heed. 46 Else, did an affliction visit them for that their own hands have forwarded then they might say, 'Our Lord, why didst Thou not send a Messenger to us that we might follow Thy signs and so be among the believers?' 47 But when the truth came to them from Us, they said, "Why has he not been given the like of what Moses was given?" But did they not reject what Moses was given before? They said, "Both [Moses and Muhammad] are kinds of sorcery, each assisting the other." And they add, "We reject both of them." 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 Then, if they cannot give you an answer, know that they are only following their lusts. And who can be farther astray than he who follows his lust without any guidance from God? And certainly God does not guide an unjust people. 50
