اللَّهُمَّ إِنَّكَ عَفُوٌّ كَرِيمٌ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي
Allahumma innaka 'Afuwwun Karimun tuhibbul-'afwa fa'fu 'anni
O Allah, You are the Pardoner, the Most Generous, and You love to pardon, so pardon me.
This expanded version adds "Karim" (the Most Generous) to the du'a Aisha (RA) was taught for Laylatul Qadr. Al-'Afuww means the One who erases sins completely — not just forgives them, but wipes them out as though they never existed.
