And We gave Moses the Book, after We had destroyed the former generations, to be reflections for people and a guidance, and a mercy in order that they might remember. 43 And you, [O Muhammad], were not on the western side [of the mount] when We revealed to Moses the command, and you were not among the witnesses [to that]. 44 But We brought forth generations, and their lives dragged on for them. And thou wast not a dweller in Midian, reciting unto them Our revelations, but We kept sending (messengers to men). 45 And neither wert thou present on the slope of Mount Sinai when We called out [to Moses]: but [thou, too, art sent] as an act of thy Sustainer's grace, to warn people to whom no warner has come before thee, so that they might bethink themselves [of Us]; 46 and may not say, if an affliction should befall them on account of their misdeeds: "Lord, if only You had sent us a messenger, we might have followed Your message and become 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 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
