And when he attained his full strength and was [mentally] mature, We bestowed upon him judgement and knowledge. And thus do We reward the doers of good. 14 And he entered the city at a time of unawareness of its people, and he found there two men fighting, - one of his party (his religion - from the Children of Israel), and the other of his foes. The man of his (own) party asked him for help against his foe, so Musa (Moses) struck him with his fist and killed him. He said: "This is of Shaitan's (Satan) doing, verily, he is a plain misleading enemy." 15 He said, “My Lord! I have indeed wronged my soul* therefore forgive me” – He therefore forgave him; indeed only He is the Oft Forgiving, the Most Merciful. (* By getting angry.) 16 Said he: "O my Sustainer! [I vow] by all the blessings which Thou hast bestowed on me: Nevermore shall I aid such as are lost in sin!" 17 And morning found him in the city, fearing, vigilant, when behold! he who had appealed to him the day before cried out to him for help. Moses said unto him: Lo! thou art indeed a mere hothead. 18 And when he wanted to strike the one who was an enemy to both of them, he said, "O Moses, do you intend to kill me as you killed someone yesterday? You only want to be a tyrant in the land and do not want to be of the amenders." 19 Then came a man from the furthest part of the city, running; he said, 'Moses, the Council are conspiring to slay thee. Depart; I am one of thy sincere advisers.' 20 So he left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
