When Moses reached full manhood and maturity, We bestowed upon him wisdom and knowledge: this is how We reward those who do good. 14 And he entered the city at a time of carelessness of its folk, and he found therein two men fighting, one of his own caste, and the other of his enemies; and he who was of his caste asked him for help against him who was of his enemies. So Moses struck him with his fist and killed him. He said: This is of the devil's doing. Lo! he is an enemy, a mere misleader. 15 [And] he prayed: O my Sustainer! Verily, I have sinned against myself! Grant me, then, Thy forgiveness!" And He forgave him - for, verily, He alone is truly forgiving, a dispenser of grace. 16 He said: My Lord! because Thou hast bestowed a favor on me, I shall never be a backer of the guilty. 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 Then when he decided to seize the man who was an enemy to both of them, the man said: "O Musa (Moses)! Is it your intention to kill me as you killed a man yesterday? Your aim is nothing but to become a tyrant in the land, and not to be one of those who do right." 19 And a man came running from the remotest part of the city. He said: O Musa! surely the chiefs are consulting together to slay you, therefore depart (at once); surely I am of those who wish well to you. 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
