When Moses reached full manhood and maturity, We bestowed upon him wisdom and knowledge: this is how We reward those who do good. 14 And he entered the city at a time of unawareness of the inhabitants thereof, and he found therein two men fighting, one being of his own party, and the other of his enemies. And he who was of his party, called him for help against him who was of his enemies. So Musa struck him with his fist, and put an end of him. He said: this is of the work of the Satan, verily he is an enemy, a misleader manifest. 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! Forasmuch as Thou hast favoured me, I will nevermore be a supporter of the guilty. 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 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 left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
