And certainly We gave Musa the Book after We had destroyed the former generations, clear arguments for men and a guidance and a mercy, that they may be mindful. 43 And you, [O Muhammad], were not on the western side [of the mount] when We revealed to Moses the command, and you were not among the witnesses [to that]. 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 Nor wast thou at the side of (the Mountain of) Tur when we called (to Moses). Yet (art thou sent) as Mercy from thy Lord, to give warning to a people to whom no warner had come before thee: in order that they may receive admonition. 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 If they do not respond to you, then know that they follow only their own desires. Who could be more astray than he who follows his own likes and dislikes with no guidance from God? God does not guide the evil-doers. 50
