And We gave Moses the Book, after that We had destroyed the former generations, to be examples and a guidance and a mercy, that haply so they might remember. 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 but We raised up generations, and long their lives continued. Neither wast thou a dweller among the Midianites, reciting to them Our signs; but We were sending Messengers. 45 Thou wast not upon the side of the Mount when We called; but for a mercy from thy Lord, that thou mayest warn a people to whom no warner came before thee, and that haply they may remember. 46 and [We have sent thee] lest they say [on Judgment Day,] when disaster befalls them as an outcome of what their own hands have wrought, "O our Sustainer, if only Thou had sent an apostle unto us, we would have followed Thy messages, and would have been among those who believe!" 47 But when the Truth reached them from Us, they said: "Why was he not given that which was given to Moses?" But did they not reject before what had been given to Moses? They said: "Both are magic, each supporting the other!" And they said: "We deny each of these." 48 Say: "Then bring a Book from God which gives better guidance than these so that I may follow it, if you speak the truth." 49 And if they answer thee not, then know that what they follow is their lusts. And who goeth farther astray than he who followeth his lust without guidance from Allah. Lo! Allah guideth not wrongdoing folk. 50
