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 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 He prayed, "Forgive me Lord, for I have sinned against my soul." God forgave him; for He is the Forgiving One, the Merciful. 16 He said, 'My Lord, forasmuch as Thou hast blessed me, I will never be a partisan of the sinners.' 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 So when Moosa wished to apprehend the man who was an enemy to them both, he said, “O Moosa! Do you wish to kill me the way you killed a man yesterday? You only wish to become a strict ruler in the land, and not to make reform.” 19 And there came a man, running, from the furthest end of the City. He said: "O Moses! the Chiefs are taking counsel together about thee, to slay thee: so get thee away, for I do give thee sincere advice." 20 So he left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
