LAILATUL-QADR

Its excellence As regards its excellence it is more than sufficient to mention that Lailatul-Qadr is better than a thousand months, Allaah the Mighty and Majestic, says:
"Verily! We have sent it (this Qur'aan) down in the Night of Decree (Lailatul-Qadr). And what will make you know what the Night of Decree is? The Night of Decree is better than a thousand months. Therein descend the angels and the Rooh (i.e. Gabriel) by Allaah's Permission with all Decrees, Peace! until the appearance of dawn." (Al-Qadr 97: 1-5)
And in it every decreed matter for the year is conveyed, Allaah (swt)says:
"We sent it (this Qur'aan) down on a blessed Night. Verily, We are ever warning (mankind of Our Torment). Therein (that Night) is decreed every matter of ordainment. Amran (i.e. a command or this Qur'aan or His Decree of every matter) from Us. Verily, We are ever sending (the Messenger). (As) a Mercy from your Lord. Verily! He is the All-Hearer, the All-Knower." (Ad-Dukhaan 44: 3-6)

Dua to recite on Laylat ul-Qadr

A'ishah (radhiallahu `anha) reported that she asked Allah's Messenger (sallallahu `alayhi wa sallam),

"O Messenger of Allah! If I knew which night is Laylat ul-Qadr, what should I say during it?" And he instructed her to say:

 Allahumma innaka ‘afuwwun tuhibb al-‘afwa fa’fu ‘anni (O Allah, You are All-Forgiving and You love forgiveness so forgive me).''
