And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge. And thus do We reward the doers of good. 14 He entered the city without the knowledge of its inhabitants and found two men fighting each other. One was his follower and the other his enemy. His follower asked him for help. Moses struck his enemy to death, but later said, "It was the work of satan; he is the sworn enemy of the human being and wants to mislead him". 15 He said, 'My Lord, I have wronged myself. Forgive me!' So God forgave him, for He is the All-forgiving, the All-compassionate. 16 Said he: "O my Sustainer! [I vow] by all the blessings which Thou hast bestowed on me: Nevermore shall I aid such as are lost in sin!" 17 And in the morning he was in the city fearing and looking about, when lo! he who had asked his succour yesterday was crying out unto him. Musa said: verily thou art a seducer manifest. 18 And when he sought to seize him who was an enemy unto them both, he said: O Musa wouldst thou slay me as thou didst slay a person yesterday? Thou seekest only to be a tyrant in the land, and thou seekest not to be of the reconcilers. 19 Then a man came running from the farther end of the city and said: "O Moses, the nobles are deliberating about you that they may put you to death. So do be gone. I am one of your well-wishers." 20 So he went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
