عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: يَا نَبِيَّ اللَّهِ! إِنْ وَافَقْتُ لَيْلَةَ الْقَدْرِ مَا أَقُولُ؟ قَالَ: ((تَقُولِينَ: اللَّهُمَّ إِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي))
It is narrated from Sayyidah Aisha (may Allah be pleased with her), she says: O Messenger of Allah! If I find the Night of Qadr, which supplication should I make? The Prophet (peace and blessings be upon him) said: Make this supplication: "Allahumma innaka ‘afuwwun tuhibbul ‘afwa fa‘fu ‘anni." (O Allah! You are Forgiving, You love forgiveness, so forgive me.)
