Surah Al-Qasas (The Stories), Verse 16

قَالَ رَبِّ اِنِّیْ ظَلَمْتُ نَفْسِیْ فَاغْفِرْ لِیْ فَغَفَرَ لَهٗ اِنَّهٗ هُوَ الْغَفُوْرُ الرَّحِیْمُ ۟

Qaala Rabbi innee zalamtu nafsee faghfir lee faghafaralah; innahoo Huwal Ghafoorur Raheem

“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.”
