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 (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 nay, but [between them and thee] We brought into being [many] generations, and long was their span of life. And neither didst thou dwell among the people of Madyan, conveying Our messages unto them: nay, but We have [always] been sending [Our message-bearers unto man]. 45 You were not present on the side of the Tor when We called. Yet as a mercy from your Lord to warn a nation to whom no warner has been sent before, in order that they remember 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 (i.e. Muhammad SAW with his Message) has come to them from Us, they say: "Why is he not given the like of what was given to Musa (Moses)? Did they not disbelieve in that which was given to Musa (Moses) of old? They say: "Two kinds of magic [the Taurat (Torah) and the Quran] each helping the other!" And they say: "Verily! In both we are disbelievers." 48 Say: 'Bring a Book from God that gives better guidance than these, and follow it, if you speak truly.' 49 But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people. 50
