After destroying the people of the ancient towns We gave the Book to Moses to be a source of knowledge, a guidance, and mercy for mankind so that perhaps they would take heed. 43 (O Muhammad), you were then not on the western side when We bestowed this commandment (of Law), and you were not among its witnesses. 44 We raised (many more) generations and prolonged their lives. You did not live with the people of Midian, nor recited to them Our revelations; but We kept on sending 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 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 Yet when the truth came to them 'from Ourselves, they said, 'Why has he not been given the like' of that Moses was given?' But they, did they not disbelieve also in what Moses was given aforetime? They said, 'A pair of sorceries mutually supporting each other.' 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
