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 when its people were not watching: and he found there two men fighting,- one of his own religion, and the other, of his foes. Now the man of his own religion appealed to him against his foe, and Moses struck him with his fist and made an end of him. He said: "This is a work of Evil (Satan): for he is an enemy that manifestly misleads!" 15 [And] he prayed: O my Sustainer! Verily, I have sinned against myself! Grant me, then, Thy forgiveness!" And He forgave him - for, verily, He alone is truly forgiving, a dispenser of grace. 16 He said: my Lord! whereas Thou hast favoured me, I shall nevermore be a supporter of the culprits. 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, fearful and hesitant, (and) prayed: "O Lord, deliver me from these wicked people." 21
