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 You were not present on the western side of the Mount when We gave Our Command to Moses: nor were you among the witnesses, 44 But We raised many generations after Moses and they lived for many years. You did not dwell with the people of Midian reciting Our revelations to them, but We had certainly sent Messengers to them. 45 Nor wast thou beside the Tur when We called; but thou art sent as a mercy from thy Lord, that thou mayest warn a people unto whom no warner came before thee, that haply they might be admonished. 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 When the Truth from Us came to them they said, "Would that he, (Muhammad), had received what was given to Moses (by his Lord)." Did not they reject what Moses had brought to them saying, "These two, Moses and Aaron, are two magicians who support each other. We do not have any faith in them." 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
