The Superiority of Lailat-ul-Qadr (the Night of Decree)
وعنها قَالَتْ: قُلْتُ: يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِنْ عَلِمْتُ أي لَيْلَةٍ الْقَدْرِ مَا أَقُولُ فِيهَا؟ قَالَ: قُولِي: اللَّهُمَّ إِنَّكَ عَفُوٌّ تُحِبُّ الْعَفْوَ فَاعَفُ عَنِّي ((رَوَاهُ التِّرْمِذِيّ وَقَالَ حَدِيثٌ حَسَنٌ صَحِيحٌ))
'Aishah (May Allah be pleased with her) reported: I asked: "O Messenger of Allah! If I realize Lailat-ul-Qadr (Night of Decree), what should I supplicate in it?" He (ﷺ) replied, "You should supplicate: Allahumma innaka 'afuwwun, tuhibbul-'afwa, fa'fu 'anni (O Allah, You are Most Forgiving, and You love forgiveness; so forgive me)." [At-Tirmidhi].
