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

Allāhumma anta rabbī, lā ilāha illā ant, khalaqtanī wa ana 'abduk, wa ana 'alā 'ahdika wa wa'dika mastaṭa't, a'ūdhu bika min sharri mā ṣana't, abū'u laka bini'matika 'alayya, wa abū'u laka bidhanbī, faghfir lī, fa innahū 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 to 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 favour upon me, and I acknowledge my sin, so forgive me, for none forgives sins but You.
