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 Thou wast not on the Western side when We decreed the Commission to Moses, nor wast thou a witness (of those events). 44 Thereafter We raised up many a generation and a long time passed. You were then not even present among the people of Midian to rehearse Our verses to them. But it is We Who are sending news about that. 45 Nor were you on the side of the Mount (Sinai) when We called out to Moses (in the first instance). But it is out of Mercy from your Lord (that you are being informed of all this) so that you may warn a people to whom no warner came before you. Maybe they will take heed. 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 (now), when the Truth has come to them from Ourselves, they say, "Why are not (Signs) sent to him, like those which were sent to Moses?" Do they not then reject (the Signs) which were formerly sent to Moses? They say: "Two kinds of sorcery, each assisting the other!" And they say: "For us, we reject all (such things)!" 48 Say: 'Bring a Book from God that gives better guidance than these, and follow it, if you speak truly.' 49 So if they do not accept your challenge, then know that they only follow their desires; and who is more astray than one who follows his desires away from the guidance of Allah? Indeed Allah does not guide the unjust. 50
