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 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 you were not on the side of the Mount when We called out to Moses, but We have sent you as a mercy from your Lord, so that you may warn people to whom no warner has been sent before you, so that they may take heed, 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 But when the truth came to them from Us, they said: "Why is he not given the like of what was given to Moses?" Did they not disbelieve before in what was given to Moses? They said: "Both are imposters one like the other," and added: "We do not believe in either." 48 Say (unto them, O Muhammad): Then bring a scripture from the presence of Allah that giveth clearer guidance than these two (that) I may follow it, if ye are truthful. 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
