And [then,] indeed, after We had destroyed those earlier generations [of sinners,] We vouchsafed unto Moses [Our] revelation as a means of insight for men, and as a guidance and grace, so that they might bethink themselves [of Us]. 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 But We brought forth generations, and their lives dragged on for them. And thou wast not a dweller in Midian, reciting unto them Our revelations, but We kept sending (messengers to men). 45 And neither wert thou present on the slope of Mount Sinai when We called out [to Moses]: but [thou, too, art sent] as an act of thy Sustainer's grace, to warn people to whom no warner has come before thee, so that they might bethink themselves [of Us]; 46 to whom no warner had been sent that perhaps they might take heed, and that, on experiencing afflictions because of their own deeds, they may not say, "Lord, would that You had sent to us a Messenger so that we could follow Your revelations and become believers". 47 Yet when the truth is come unto them from before Us, they say: wherefore hast he not been vouchsafed the like of that which was given unto Musa? Disbelieved they not in that which was given unto Musa aforetime? They say; two magics supporting each other. And they say: verily in all such things we are disbelievers. 48 (Muhammad), tell them, "Bring a Book if you are able to, from God better in its guidance than the Torah and the Quran; I shall follow it". 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
