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 unnoticed by the people and found two men fighting, one was of his own party, and the other of his enemies.

Forgive me!" The Lord forgave him; He is All-forgiving and All-merciful. 16 He said: "My Lord! For that with which You have favoured me, I will never more be a helper for the Mujrimun (criminals, disobedient to Allah, polytheists, sinners, etc.)!" 17 In the morning, he was in the city, fearful and vigilant, then he whom he had helped the day before cried out to him again for help. 'Clearly' said Moses, 'you are quarrelsome' 18 When Moses was about to attack their enemy, he said, "Moses, do you want to kill me as you slew a soul the other day? Do you want to become a tyrant in the land, not a reformer?" 19 Then a man came running from the furthest part of the city, 'Moses' he said, 'the Assembly are plotting to kill you. Leave, for I am one of your sincere advisers' 20 So he went forth from thence, looking fearfully about him, and prayed: "O my Sustainer! Save me from all evildoing folk!" 21
