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 Thou wast not upon the western side when We decreed to Moses the commandment, nor wast thou of those witnessing; 44 We brought into being many generations who lived long lives, nor did you live among the people of Midian and recite our revelations to them, it is We who send messengers, 45 And you were not at the side of the mount when We called [Moses] but [were sent] as a mercy from your Lord to warn a people to whom no warner had come before you that they might be reminded. 46 (We did so) lest a calamity might seize them because of the misdeeds they committed whereafter they would say: "Our Lord, why did you not send a Messenger to us that we follow Your revelation and become among those who believe?" 47 But when the truth came to them from Us, they said, "Why was he not given like that which was given to Moses?" Did they not disbelieve in that which was given to Moses before? They said, "[They are but] two works of magic supporting each other, and indeed we are, in both, disbelievers." 48 Say: 'Bring a Book from God that gives better guidance than these, and follow it, if you speak truly.' 49 And since they cannot respond to this thy challenge, know that they are following only their own likes and dislikes: and who could be more astray than he who follows [but] his own likes and dislikes without any guidance from God? Verily, God does not grace with His guidance people who are given to evildoing! 50
