And [then,] indeed, after We had destroyed those earlier generations [of sinners,] We vouchsafed unto Moses [Our] revelation as a means of insight for men, and as a guidance and grace, so that they might bethink themselves [of Us]. 43 Thou wast not on the Western side when We decreed the Commission to Moses, nor wast thou a witness (of those events). 44 but We raised up generations, and long their lives continued. Neither wast thou a dweller among the Midianites, reciting to them Our signs; but We were 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 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 reached them from Us, they said: "Why was he not given that which was given to Moses?" But did they not reject before what had been given to Moses? They said: "Both are magic, each supporting the other!" And they said: "We deny each of these." 48 Tell them, (O Prophet): "Then do bring a Book from Allah which is a better guide than either of them, and I will follow it! Do so if you 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
