And when he reached his maturity and full strength, We gave him wisdom and knowledge; and this is how We reward the virtuous. 14 And he entered the city, at a time when its people were unheeding, and found there two men fighting; the one was of his own party, and the other was of his enemies. Then the one that was of his party cried to him to aid him against the other that was of his enemies; so Moses struck him, and despatched him, and said, 'This is of Satan's doing; he is surely an enemy misleading, manifest.' 15 He said, "My Lord, indeed I have wronged myself, so forgive me," and He forgave him. Indeed, He is the Forgiving, the Merciful. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of the guilty." 17 He remained in the city but very afraid and cautious. Suddenly the person who asked him for help the previous day asked him for help again. Moses said, "You are certainly a mischievous person". 18 And when he would have fallen upon the man who was an enemy unto them both, he said: O Moses! Wouldst thou kill me as thou didst kill a person yesterday. Thou wouldst be nothing but a tyrant in the land, thou wouldst not be of the reformers. 19 There came a man running from the other part of the city. "O Moses," he said, "the chiefs are deliberating to kill you. Go away from the city. I wish you well." 20 So he left it, fearful and anticipating [apprehension]. He said, "My Lord, save me from the wrongdoing people." 21
