After We had destroyed the earlier generations, We gave Moses the Book to give men insight, and as guidance and a blessing for people, so that they might take heed. 43 And you, [O Muhammad], were not on the western side [of the mount] when We revealed to Moses the command, and you were not among the witnesses [to that]. 44 We brought into being many generations who lived long lives, nor did you live among the people of Midian and recite our revelations to them, it is We who send messengers, 45 You had not been present at the side of the Mount (Sinai) when We called Moses (from the tree), but through Our mercy we told you his story so that you might warn the people 46 (We did so) lest a calamity might seize them because of the misdeeds they committed whereafter they would say: "Our Lord, why did you not send a Messenger to us that we follow Your revelation and become among those who believe?" 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 If they do not answer you, know that they are only following their desires. And who is further astray than he who is led by his desires without guidance from Allah! Allah does not guide the harmdoers. 50
