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 "O Lord," he prayed, "I have done wrong, forgive me." And God forgave him. Verily He is forgiving and kind. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of the guilty." 17 So he became afraid, looking about in the city (waiting as to what will be the result of his crime of killing), when behold, the man who had sought his help the day before, called for his help (again). Musa (Moses) said to him: "Verily, you are a plain misleader!" 18 And when Moses was about to seize he who was the enemy of both of them, he said: 'Moses, would you kill me as you killed a living soul yesterday? You desire only to be a tyrant in the land, and you do not want to be among the reformers' 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 So he left, fearful and vigilant, saying: 'My Lord, save me from the harmdoing nation' 21
