Sayyidul Istighfar Dua for Forgiveness

اَللَّهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ، خَلَقْتَنِيْ وَأَنَا عَبْدُكَ وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ، أَعُوْذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ أَبُوءُ لَكَ بِنِعْمَتِكَ عَلَيَّ، وَأَبُوءُ بِذَنْبِيْ فَاغْفِرْ لِي فَإِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ

Allaahumma anta rabbee laa ilaaha illaa anta, khalaqtanee wa-ana ‘abduka, wa-ana ‘alaa ‘ahdika wawa‘dika mas-tata‘tu, a‘oothu bika min sharri maa sana‘tu, aboo-o laka bini‘matika ‘alayya, wa-aboo-o bithanbee, faghfir lee fa-innahu laa yaghfirudh dhunooba illaa anta

Meaning

O Allah, You are my Lord, none has the right to be worshipped except You, You created me and I am Your servant and I abide to Your covenant and promise as best I can, I take refuge in You from the evil of which I have committed. I acknowledge Your favour upon me and I acknowledge my sin, so forgive me, for verily none can forgive sin except You.
