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 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! For that with which You have favoured me, I will never more be a helper for the Mujrimun (criminals, disobedient to Allah, polytheists, sinners, etc.)!" 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 Then, when he decided to lay hold of the man who was an enemy to both of them, that man said: "O Moses! Is it thy intention to slay me as thou slewest a man yesterday? Thy intention is none other than to become a powerful violent man in the land, and not to be one who sets things right!" 19 Then a man came running from the furthest part of the city, 'Moses' he said, 'the Assembly are plotting to kill you. Leave, for I am one of your sincere advisers' 20 So he went forth from thence fearing, looking about. He said: my Lord! deliver me from the wrong-doing people. 21
