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 And he entered the city at a time of unawareness of its people, and he found there two men fighting, - one of his party (his religion - from the Children of Israel), and the other of his foes. The man of his (own) party asked him for help against his foe, so Musa (Moses) struck him with his fist and killed him. He said: "This is of Shaitan's (Satan) doing, verily, he is a plain misleading enemy." 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! The way You have bestowed favour upon me, so never will I be a supporter of the guilty.” 17 And he became inside the city fearful and anticipating [exposure], when suddenly the one who sought his help the previous day cried out to him [once again]. Moses said to him, "Indeed, you are an evident, [persistent] deviator." 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
