اَللّٰهُمَّ اَنْتَ رَبِّيْ ، لَا اِلٰهَ اِلَّا اَنْتَ خَلَقْتَنِيْ وَاَنَا عَبْدُكَ ، وَاَنَا عَلَی عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ اَعُوْذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ ، اَبُوْءُ لَكَ بِنِعْمَتِكَ عَلَيَّ ، وَ اَبُوْءُ بِذَنْبِي ، فَاغْفِرْ لِيْ ، فَاِنَّهُ لَا يَغْفِرُ الذُّنُوْبَ اِلَّا اَنْتَ

O Allah! You are my Rabb. There is no true god except You. You have created me, and I am Your slave, and I hold to Your Covenant as far as I can. I seek refuge in You from the evil of what I have done. I acknowledge the favors that You have bestowed upon me, and I confess my sins. Pardon me, for none but You has the power to pardon
