Making Supplications:

It is also recommended to make extensive supplication on this night. ‘A'ishah reported that she asked Allah’s Messenger (Sallallahu alaihi wa sallam) “O Messenger of Allah! If I knew which night is Laylatul Qadr, what should I say during it?” And he instructed her to say: “Allahumma innaka `afuwwun tuhibbul `afwa fa`fu `annee - O Allah! You are forgiving, and you love forgiveness. So forgive me.” [An authentic Hadith recorded by Ahmad, Ibn Majah and at-Tirmidhi.]
