Now when [Moses] reached full manhood and had become mature [of mind]. We bestowed upon him the ability to judge [between right and wrong] as well as [innate] knowledge: for thus do We reward the doers of 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! Forasmuch as Thou hast favoured me, I will nevermore be a supporter of the guilty. 17 So he saw the morning in the city, looking about, in a state of fear, when behold, the man who had, the day before, sought his help called aloud for his help (again). Moses said to him: "Thou art truly, it is clear, a quarrelsome fellow!" 18 And when he sought to seize him who was an enemy unto them both, he said: O Musa wouldst thou slay me as thou didst slay a person yesterday? Thou seekest only to be a tyrant in the land, and thou seekest not to be of the reconcilers. 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 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
