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 You were not there on the western side (of Mount Sinai) when We gave the commandments to Moses, nor were you witness (to the event). 44 Thereafter We raised up many a generation and a long time passed. You were then not even present among the people of Midian to rehearse Our verses to them. But it is We Who are sending news about that. 45 And you were not on this side of the mountain when We called, but a mercy from your Lord that you may warn a people to whom no warner came before you, that they may be mindful. 46 If (We had) not (sent thee to the Quraish),- in case a calamity should seize them for (the deeds) that their hands have sent forth, they might say: "Our Lord! why didst Thou not sent us a messenger? We should then have followed Thy Signs and been amongst those who believe!" 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 Then if they answer thee not, know thou that they only follow their own desires; and who is farther astray than he who followeth his desire without guidance from Allah? Verily Allah guideth not a wrong-doing people. 50
