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 (O Muhammad SAW) were not on the western side (of the Mount), when We made clear to Musa (Moses) the commandment, and you were not among those present. 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 And nor were you beside the Mount when We proclaimed – however it is a mercy from your Lord* so that you may warn a nation towards whom no Herald of Warning came before you, in the hope of their heeding advice. (*That He has bestowed knowledge of the hidden to you) 46 Otherwise, if disaster should afflict them because of that which their own hands have sent before (them), they might say: Our Lord! Why sentest Thou no messenger 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: 'If what you say is true, bring down from Allah a Book that is a better guidance than both, I will follow it' 49 If they do not answer you, know that they are only following their desires. And who is further astray than he who is led by his desires without guidance from Allah! Allah does not guide the harmdoers. 50
