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 went into the city at a time of unvigilance on the part of its people, so he found therein two men fighting, one being of his party and the other of his foes, and he who was of his party cried out to him for help against him who was of his enemies, so Musa struck him with his fist and killed him. He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray. 15 He said, 'My Lord, I have wronged myself. Forgive me!' So God forgave him, for He is the All-forgiving, the All-compassionate. 16 He said, "Lord, in appreciation for Your favor to me I shall never support the criminals". 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 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 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 in fear, waiting to see what happens; he said, “My Lord! Rescue me from the unjust people.” 21
