And when he attained his maturity and became full grown, We granted him wisdom and knowledge; and thus do We reward those who do good (to others). 14 He entered the city unnoticed by its people, and there he encountered two men fighting with one another -- one of his own people and the other one of his enemies. The one who belonged to his own people cried out to him for help against his foe -- whereupon Moses struck him down with his fist, thereby causing his death. Moses said, "This is Satan's doing; he is an open foe, leading man astray." 15 He said: My Lord! Lo! I have wronged my soul, so forgive me. Then He forgave him. Lo! He is the Forgiving, the Merciful. 16 He said: My Lord! Forasmuch as Thou hast favoured me, I will nevermore be a supporter of the guilty. 17 In the morning he came to the city, fearful and hesitant. Just then he who had asked him for help the day before called out for help (again). "You are indeed a meddlesome fellow," Moses said to him. 18 When he wanted to catch the one who was an enemy to them both, the man said, "Moses, do you want to kill me just as you killed a man yesterday? You only want to become a tyrant in the land; you do not want to set things right." 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 Moses departed from the city, fearful and vigilant, and prayed, "My Lord, save me from these unjust people." 21
