When he become matured and grow to manhood, We granted him wisdom and knowledge.

He said: This is on account of the Shaitan's doing; surely he is an enemy, openly leading astray. 15 Forgive me, my Lord, for I have wronged myself' and so He forgave him; for He is indeed the Forgiving, the Most Merciful. 16 He said, "My Lord, because of the favour that You have shown me, I vow that I will never be a helper of the guilty." 17 And he became inside the city fearful and anticipating [exposure], when suddenly the one who sought his help the previous day cried out to him [once again]. Moses said to him, "Indeed, you are an evident, [persistent] deviator." 18 Then as he was about to lay hands on the one who was their common enemy, he cried out: "O Moses, do you want to kill me as you killed that person yesterday? You only want to be a tyrant in the land and no peacemaker." 19 Then a man came running from the farther end of the city and said: "O Moses, the nobles are deliberating about you that they may put you to death. So do be gone. I am one of your well-wishers." 20 So he left the city afraid and cautious, saying, "Lord, protect me against the unjust people". 21
