After destroying the people of the ancient towns We gave the Book to Moses to be a source of knowledge, a guidance, and mercy for mankind so that perhaps they would take heed. 43 And thou (Muhammad) wast not on the western side (of the Mount) when We expounded unto Moses the commandment, and thou wast not among those present; 44 However, We created generations and ages passed by upon them; and nor were you dwelling with the people of Madyan reciting Our verses to them – however it is We Who made the Noble Messengers. 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 Say to them, "Bring down from God a scripture that is a better guide than these two and I will follow it, if what you say be true." 49 But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people. 50
