After destroying the people of the ancient towns We gave the Book to Moses to be a source of knowledge, a guidance, and mercy for mankind so that perhaps they would take heed. 43 And you were not on the western side when We revealed to Musa the commandment, and you were not among the witnesses; 44 We raised (many more) generations and prolonged their lives. You did not live with the people of Midian, nor recited to them Our revelations; but We kept on sending messengers. 45 And nor were you beside the Mount when We proclaimed – however it is a mercy from your Lord* so that you may warn a nation towards whom no Herald of Warning came before you, in the hope of their heeding advice. (*That He has bestowed knowledge of the hidden to you) 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 When the Truth from Us came to them they said, "Would that he, (Muhammad), had received what was given to Moses (by his Lord)." Did not they reject what Moses had brought to them saying, "These two, Moses and Aaron, are two magicians who support each other. We do not have any faith in them." 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 But if they hearken not to thee, know that they only follow their own lusts: and who is more astray than one who follow his own lusts, devoid of guidance from Allah? for Allah guides not people given to wrong-doing. 50
