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 wast not on the western side when We decreed the affair unto Musa, and thou wast not of the witnesses. 44 We raised generations who lived long. You did not live among the people of Midian, nor did you recite to them Our verses; but We were sending Messengers. 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 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 Then if they do not answer thee, know that they are only following their caprices; and who is further astray than he who follows his caprice without guidance from God? Surely God guides not the people of the evildoers. 50
