And assuredly We vouchsafed the Scripture unto Musa after We had destroyed the generations of old; enlightenment unto mankind and a guidance and a mercy, that haply they might be admonished. 43 And you were not on the western side when We revealed to Musa the commandment, and you were not among the witnesses; 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 Nor were you on the side of the Mount (Sinai) when We called out to Moses (in the first instance). But it is out of Mercy from your Lord (that you are being informed of all this) so that you may warn a people to whom no warner came before you. Maybe they will take heed. 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 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: 'If what you say is true, bring down from Allah a Book that is a better guidance than both, I will follow it' 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
