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 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 "O Lord," he prayed, "I have done wrong, forgive me." And God forgave him. Verily He is forgiving and kind. 16 He said: "O my Lord! For that Thou hast bestowed Thy Grace on me, never shall I be a help to those who sin!" 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 When Moses was about to attack their enemy, he said, "Moses, do you want to kill me as you slew a soul the other day? Do you want to become a tyrant in the land, not a reformer?" 19 A man came running from the farthest part of the city saying, "Moses, people are planning to kill you. I sincerely advise you to leave the city. 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
