When he become matured and grow to manhood, We granted him wisdom and knowledge. Thus do We reward the righteous ones. 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 prayed: "O my Lord! I have indeed wronged my soul! Do Thou then forgive me!" So (Allah) forgave him: for He is the Oft-Forgiving, Most Merciful. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of the guilty." 17 He remained in the city but very afraid and cautious. Suddenly the person who asked him for help the previous day asked him for help again. Moses said, "You are certainly a mischievous person". 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 And a man came running from the outer part of the city; he said, “O Moosa! Indeed the court members are considering killing you, therefore go away – I surely am your well-wisher.” 20 So he departed therefrom, fearful and vigilant; he said, 'My Lord, deliver me from the people of the evildoers.' 21
