The Master Supplication for Seeking Forgiveness
اَللّٰهُمَّ أَنْتَ رَبِّيْ لَا إِلٰهَ إِلَّا أَنْتَ ، خَلَقْتَنِيْ وَأَنَا عَبْدُكَ ، وَأَنَا عَلَىٰ عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ ، أَعُوْذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ ، أَبُوْءُ لَكَ بِنِعْمَتِكَ عَلَيَّ وَأَبُوْءُ لَكَ بِذَنْبِيْ ، فَاغْفِرْ لِيْ فَإِنَّهُ لَا يَغْفِرُ الذُّنُوْبَ إِلَّا أَنْتَ.
O Allah, You are my Lord; there is no god but You. You created me and I am Your servant, and I hold to Your covenant and Your promise as far as I am able. I seek refuge in You from the evil of what I have done. I acknowledge Your favour upon me, and I acknowledge my sin to You. So forgive me, for no one forgives sins except You.
