And We verily gave the Scripture unto Moses after We had destroyed the generations of old: clear testimonies for mankind, and a guidance and a mercy, that haply they might reflect. 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 But We raised up generations, then life became prolonged to them; and you were not dwelling among the people of Madyan, reciting to them Our communications, but We were the senders. 45 You had not been present at the side of the Mount (Sinai) when We called Moses (from the tree), but through Our mercy we told you his story so that you might warn the people 46 (We did so) lest a calamity might seize them because of the misdeeds they committed whereafter they would say: "Our Lord, why did you not send a Messenger to us that we follow Your revelation and become among those who believe?" 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: '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
