After We had destroyed the earlier generations We bestowed the Book on Moses - a source of enlightenment for people and a guidance and mercy -- that they may take heed. 43 Thou wast not on the Western side when We decreed the Commission to Moses, nor wast thou a witness (of those events). 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 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 Otherwise, if some disaster befell them because of what their own hands have sent forward they would say, “Our Lord! Why did you not send a Noble Messenger towards us, so we may have followed Your signs and accepted faith?” 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 respond to you - then know that they only follow their [own] desires. And who is more astray than one who follows his desire without guidance from Allah? Indeed, Allah does not guide the wrongdoing people. 50
