When Moses reached full manhood and maturity, We bestowed upon him wisdom and knowledge: this is how 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 Then he prayed: "My Lord! I have indeed inflicted wrong on myself, so do forgive me," wherefore Allah forgave him for He is Ever Forgiving, Most Merciful. 16 He said: my Lord! whereas Thou hast favoured me, I shall nevermore be a supporter of the culprits. 17 In the morning, he was in the city, fearful and vigilant, then he whom he had helped the day before cried out to him again for help. 'Clearly' said Moses, 'you are quarrelsome' 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 And a man came from the farthest end of the city, running. He said, "O Moses, indeed the eminent ones are conferring over you [intending] to kill you, so leave [the city]; indeed, I am to you of the sincere advisors." 20 He therefore got away therefrom, looking about, in a state of fear. He prayed "O my Lord! save me from people given to wrong-doing." 21
