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 unnoticed by the people and found two men fighting, one was of his own party, and the other of his enemies. The one of his party appealed for his help against his enemy, Moses struck and killed him, and said: 'This is the work of satan, he is surely a clear, misleading enemy. 15 (Moses) said, "Lord, I have wronged myself. Forgive me!" The Lord forgave him; He is All-forgiving and All-merciful. 16 Thereupon Moses vowed: "My Lord, because of the favour that You have done me I shall never support the guilty." 17 Now in the morning he was in the city, fearful and vigilant; and behold, the man who had sought his, succour on the day before cried out to him again. Moses said to him, 'Clearly thou art, a quarreller.' 18 Then as he was about to lay hands on the one who was their common enemy, he cried out: "O Moses, do you want to kill me as you killed that person yesterday? You only want to be a tyrant in the land and no peacemaker." 19 And a man came running from the outer part of the city; he said, “O Moosa! Indeed the court members are considering killing you, therefore go away – I surely am your well-wisher.” 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
