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 And you were not on the western side when We revealed to Musa the commandment, and you were not among the witnesses; 44 But We produced [many] generations [after Moses], and prolonged was their duration. And you were not a resident among the people of Madyan, reciting to them Our verses, but We were senders [of this message]. 45 you were not on the side of the Mount when We called out to Moses, but We have sent you as a mercy from your Lord, so that you may warn people to whom no warner has been sent before you, so that they may take heed, 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 came to them from Us, they said, "Why has he not been given the like of what Moses was given?" But did they not reject what Moses was given before? They said, "Both [Moses and Muhammad] are kinds of sorcery, each assisting the other." And they add, "We reject both of them." 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
