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

Allāhumma anta rabbī, lā ilāha illā ant, khalaqtanī wa anā ʿabduk, wa anā ʿalā ʿahdika wa waʿdika mastaṭaʿt, aʿūdhu bika min sharri mā ṣanaʿt, abū'u laka bi-niʿmatika ʿalayya, wa abū'u bi-dhanbī, faghfir lī, fa innahu lā yaghfirudh-dhunūba illā ant

O Allah, You are my Lord, there is no god but You. You created me and I am Your servant, and I keep Your covenant and promise as best 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 but You.
