The master of seeking forgiveness

اللَّهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ، خَلَقْتَنِي وَأَنَا عَبْدُكَ، وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ، أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ، أَبُوءُ لَكَ بِنِعْمَتِكَ عَلَيَّ، وَأَبُوءُ بِذَنْبِي، فَاغْفِرْ لِي، فَإِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ

Allahumma anta Rabbi la ilaha illa anta, khalaqtani wa ana 'abduka...

O Allah, You are my Lord; there is no god but You. You created me and I am Your servant. I keep Your covenant and promise as much as I can. I seek refuge in You from the evil of what I have done. I acknowledge Your favor upon me, and I acknowledge my sin, so forgive me, for none forgives sins except You.
