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 And you were not on the western side when We revealed to Musa the commandment, and you were not among the witnesses; 44 But We produced [many] generations [after Moses], and prolonged was their duration. And you were not a resident among the people of Madyan, reciting to them Our verses, but We were senders [of this message]. 45 Nor wast thou beside the Tur when We called; but thou art sent as a mercy from thy Lord, that thou mayest warn a people unto whom no warner came before thee, that haply they might be admonished. 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 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 Say: "Produce, then, [another] revelation from God which would offer better guidance than either of these two [and] I shall follow it, if you speak the truth!" 49 And if they answer thee not, then know that what they follow is their lusts. And who goeth farther astray than he who followeth his lust without guidance from Allah. Lo! Allah guideth not wrongdoing folk. 50
