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 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 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 And yet, now that the truth has come unto them from Us, they say: "Why has he not been vouchsafed the like of what Moses was vouchsafed?" But did they not also, before this, deny the truth of what Moses was vouchsafed? [For] they do say: "Two examples of delusion, [seemingly] supporting each other!" And they add, "Behold, we refuse to accept either of them as true!" 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 And since they cannot respond to this thy challenge, know that they are following only their own likes and dislikes: and who could be more astray than he who follows [but] his own likes and dislikes without any guidance from God? Verily, God does not grace with His guidance people who are given to evildoing! 50
