And We verily gave the Scripture unto Moses after We had destroyed the generations of old: clear testimonies for mankind, and a guidance and a mercy, that haply they might reflect. 43 (O Muhammad), you were then not on the western side when We bestowed this commandment (of Law), and you were not among its witnesses. 44 However, We created generations and ages passed by upon them; and nor were you dwelling with the people of Madyan reciting Our verses to them – however it is We Who made the Noble Messengers. 45 Nor wast thou at the side of (the Mountain of) Tur when we called (to Moses). Yet (art thou sent) as Mercy from thy Lord, to give warning to a people to whom no warner had come before thee: in order that they may receive admonition. 46 And if not that a disaster should strike them for what their hands put forth [of sins] and they would say, "Our Lord, why did You not send us a messenger so we could have followed Your verses and been among the believers?"... 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: Then bring some (other) book from Allah which is a better guide than both of them, (that) I may follow it, if you are truthful. 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
