When Moses reached the age of full youth and grew to maturity, We bestowed upon him wisdom and knowledge. Thus do We reward those who do good. 14 He came to the city when the people were in a care-free mood, and saw two men quarrelling, one belonging to his community, the other to his enemies. The man who belonged to his community appealed for help against the one who belonged to the enemies. Moses struck him a blow with his fist and finished him off. "This is of Satan's doing," he said. "He is certainly an enemy and a corrupter." 15 He said, 'My Lord, I have wronged myself. Forgive me!' So God forgave him, for He is the All-forgiving, the All-compassionate. 16 He said: My Lord! Forasmuch as Thou hast favoured me, I will nevermore 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 And when he wanted to strike the one who was an enemy to both of them, he said, "O Moses, do you intend to kill me as you killed someone yesterday? You only want to be a tyrant in the land and do not want to be of the amenders." 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 escaped from there, looking about in a state of fear. He said: "My Lord! Save me from the people who are Zalimun (polytheists and wrong-doers)!" 21
