And We verily gave the Scripture unto Moses after We had destroyed the generations of old: clear testimonies for mankind, and a guidance and a mercy, that haply they might reflect. 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 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 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 Say: "Then bring a Book from God which gives better guidance than these so that I may follow it, if you speak the truth." 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
