And when he was fully grown and in the perfection of his strength, We gave him judgment and knowledge; even so do We recompense the good-doers. 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 prayed, "Forgive me Lord, for I have sinned against my soul." God forgave him; for He is the Forgiving One, the Merciful. 16 He said: "O my Lord! For that Thou hast bestowed Thy Grace on me, never shall I be a help to those who sin!" 17 Now in the morning he was in the city, fearful and vigilant; and behold, the man who had sought his, succour on the day before cried out to him again. Moses said to him, 'Clearly thou art, a quarreller.' 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 the city in fear, waiting to see what happens; he said, “My Lord! Rescue me from the unjust people.” 21
