اللَّهُمَّ أَنْتَ رَبِّي لَا إِلَٰهَ إِلَّا أَنْتَ، خَلَقْتَنِي وَأَنَا عَبْدُكَ، وَأَنَا عَلَىٰ عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ، أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ، أَبُوءُ لَكَ بِنِعْمَتِكَ عَلَيَّ، وَأَبُوءُ بِذَنْبِي، فَاغْفِرْ لِي فَإِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ
Allahumma Anta Rabbi la ilaha illa Ant, khalaqtani wa ana 'abduk, wa ana 'ala 'ahdika wa wa'dika mastata't. A'udhu bika min sharri ma sana't. Abu'u laka bi ni'matika 'alayya wa abu'u bi dhanbi, faghfir li fa innahu la yaghfirudh-dhunuba illa Ant.
O Allah, You are my Lord, none has the right to be worshipped but You. You created me and I am Your servant. I abide by 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 except You.
Virtue
This is the master of seeking forgiveness (Sayyid al-Istighfar). Whoever says it in the morning with conviction and dies that day will enter Paradise. Likewise in the evening.
