The Superiority of Lailat-ul-Qadr (the Night of Decree)
'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 'anniاللهم إنك عفو تحب العفو فاعفُ عني(O Allah, You are Most Forgiving, and You love forgiveness; so forgive me)."[At-Tirmidhi].
