One was his follower and the other his enemy. His follower asked him for help. Moses struck his enemy to death, but later said, "It was the work of satan; he is the sworn enemy of the human being and wants to mislead him". 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 Now in the morning he was in the city, fearful and vigilant; and behold, the man who had sought his, succour on the day before cried out to him again. Moses said to him, 'Clearly thou art, a quarreller.' 18 But then as soon as he was about to lay violent hands on the man who was their [common] enemy, the latter exclaimed: "O Moses, dost thou intend to slay me as thou didst slay another man yesterday? Thy sole aim is to become a tyrant in this land, for thou dost not care to be of those who would set things to rights!" 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 went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
