After We had destroyed the earlier generations We gave Moses the Book as evidence for mankind, and a guidance and grace, so that they may remember. 43 Thou wast not on the Western side when We decreed the Commission to Moses, nor wast thou a witness (of those events). 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 Thou wast not upon the side of the Mount when We called; but for a mercy from thy Lord, that thou mayest warn a people to whom no warner came before thee, and that haply they may remember. 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: "Then bring ye a Book from Allah, which is a better guide than either of them, that I may follow it! (do), if ye are truthful!" 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
