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 He said: My Lord! Lo! I have wronged my soul, so forgive me. Then He forgave him. Lo! He is the Forgiving, the Merciful. 16 He said: 'My Lord as You have favored me, I will never be a helper to the wrongdoer' 17 And next morning he found himself in the city, looking fearfully about him, when lo! the one who had sought his help the day before [once again] cried out to him [for help whereupon] Moses said unto him: "Behold, thou art indeed, most clearly, deeply in the wrong! 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 thence, fearing, vigilant. He said: My Lord! Deliver me from the wrongdoing folk. 21
