And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge. And thus do We reward the doers of good. 14 He entered the city unnoticed by its people, and there he encountered two men fighting with one another -- one of his own people and the other one of his enemies. The one who belonged to his own people cried out to him for help against his foe -- whereupon Moses struck him down with his fist, thereby causing his death. Moses said, "This is Satan's doing; he is an open foe, leading man astray." 15 He said, “My Lord! I have indeed wronged my soul* therefore forgive me” – He therefore forgave him; indeed only He is the Oft Forgiving, the Most Merciful. (* By getting angry.) 16 Thereupon Moses vowed: "My Lord, because of the favour that You have done me I shall never support the guilty." 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 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 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
