Duas For forgiveness #7

 اللَّهُمَّ إِنِّي ظَلَمْتُ نَفْسِي ظُلْماً كَثِيراً، وَلَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ، فَاغْفِرْ لِي مَغْفِرَةً مِنْ عِنْدِكَ وَارْحَمْنِي إِنَّكَ أَنْتَ الْغَفُورُ الرَّحِيمُ

Allaahumma 'innee dhalamtu nafsee dhulman katheeran, wa laa yaghfiruth-thunooba 'illaa 'Anta, faghfir lee maghfiratan min 'indika warhamnee 'innaka 'Antal-Ghafoorur-Raheem

O Allah, I have greatly wronged myself and no one forgives sins but You. So, grant me forgiveness and have mercy on me. Surely, you are Forgiving, Merciful.

An-Nasa'i: 1303, Al-Bukhari: 834, 6326, 7387, 7388
