And certainly We gave Musa the Book after We had destroyed the former generations, clear arguments for men and a guidance and a mercy, that they may be mindful. 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 We raised (many more) generations and prolonged their lives. You did not live with the people of Midian, nor recited to them Our revelations; but We kept on sending messengers. 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 and may not say, if an affliction should befall them on account of their misdeeds: "Lord, if only You had sent us a messenger, we might have followed Your message and become believers." 47 But (now), when the Truth has come to them from Ourselves, they say, "Why are not (Signs) sent to him, like those which were sent to Moses?" Do they not then reject (the Signs) which were formerly sent to Moses? They say: "Two kinds of sorcery, each assisting the other!" And they say: "For us, we reject all (such things)!" 48 Say, "Then bring a scripture from Allah which is more guiding than either of them that I may follow it, if you should be truthful." 49 But if they hearken not to thee, know that they only follow their own lusts: and who is more astray than one who follow his own lusts, devoid of guidance from Allah? for Allah guides not people given to wrong-doing. 50
