اَللَّهُمَّ ا غْفِرْ لِيْ خَطِيْئَتِيْ وَجَهْلِيْ، وَ إِسْرَافِيْ فِيْ أَمْرِيْ، وَمَا أنْتَ أَعْلَمُ بِهِ مِنِّيْ
Allaahummagh-fir lii khatii’atii wa jahlii, wa israafii fii amrii, wa maa anta a’lamu bihii minnii. (Abu Musa al-Ash’ari Sahih al-Bukhari #5920)
O Allah, forgive my errors, my ignorance, my excesses in my affairs, and those of my wrongs that you know better than I.
Ameen
