After We had destroyed the earlier generations We bestowed the Book on Moses - a source of enlightenment for people and a guidance and mercy -- that they may take heed. 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 We raised generations who lived long. You did not live among the people of Midian, nor did you recite to them Our verses; but We were sending Messengers. 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 and [We have sent thee] lest they say [on Judgment Day,] when disaster befalls them as an outcome of what their own hands have wrought, "O our Sustainer, if only Thou had sent an apostle unto us, we would have followed Thy messages, and would have been among 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: 'Bring a Book from God that gives better guidance than these, and follow it, if you speak truly.' 49 But if they hearken not to thee, know that they only follow their own lusts: and who is more astray than one who follow his own lusts, devoid of guidance from Allah? for Allah guides not people given to wrong-doing. 50
