Dua - Laylatul Qadr
اللَّهُمَّ اِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي
Allahumma innaka 'afuwwun tuhibul 'afwa fa'fu 'anni
O Allah, You are Oft-Pardoning and You love to pardon, so pardon me.
Aisha (RA) said: “I asked the Prophet (SAW), ‘O Messenger of Allah, if I know what night is the night of Qadr, what should I say during it?’ He said: ‘Say: O Allah, You are Oft-Pardoning and You love to pardon, so pardon me.’” [Ahmad, Ibn Majah, Tirmidhi]
