Al-Qasas - 28:16

قَالَ رَبِّ إِنِّي ظَلَمْتُ نَفْسِي فَاغْفِرْ لِي فَغَفَرَ لَهُ إِنَّهُ هُوَ الْغَفُورُ الرَّحِيمُ
[28:16]
He said: My Lord! surely I have done harm to myself, so do Thou protect me. So He protected him; surely He is the Forgiving, the Merciful.
He prayed: "O my Lord! I have indeed wronged my soul! Do Thou then forgive me!" So (Allah) forgave him: for He is the Oft-Forgiving, Most Merciful.
He said: My Lord! Lo! I have wronged my soul, so forgive me. Then He forgave him. Lo! He is the Forgiving, the Merciful.
