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 went into the city at a time of unvigilance on the part of its people, so he found therein two men fighting, one being of his party and the other of his foes, and he who was of his party cried out to him for help against him who was of his enemies, so Musa struck him with his fist and killed him. He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray. 15 He said, “My Lord! I have indeed wronged my soul* therefore forgive me” – He therefore forgave him; indeed only He is the Oft Forgiving, the Most Merciful. (* By getting angry.) 16 He said: "My Lord! For that with which You have favoured me, I will never more be a helper for the Mujrimun (criminals, disobedient to Allah, polytheists, sinners, etc.)!" 17 And he was in the city, fearing, awaiting, when lo! he who had asked his assistance the day before was crying out to him for aid. Musa said to him: You are most surely one erring manifestly. 18 But when he would have assaulted the man who was an enemy to them both, the man said, 'Moses, dost thou' desire to slay me, even as thou slewest a living 'soul yesterday? Thou only desirest to be a tyrant in the land; thou desirest not to be of them that put 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 he went forth from thence fearing, looking about. He said: my Lord! deliver me from the wrong-doing people. 21
