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 But We created generations [after generations i.e. after Musa (Moses)], and long were the ages that passed over them. And you (O Muhammad SAW) were not a dweller among the people of Madyan (Midian), reciting Our Verses to them. But it is We Who kept sending (Messengers). 45 And you were not on this side of the mountain when We called, but a mercy from your Lord that you may warn a people to whom no warner came before you, that they may be mindful. 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: "Then bring ye a Book from Allah, which is a better guide than either of them, that I may follow it! (do), if ye are truthful!" 49 Then if they answer thee not, know thou that they only follow their own desires; and who is farther astray than he who followeth his desire without guidance from Allah? Verily Allah guideth not a wrong-doing people. 50
