Virtue: Laylatul Qadr is one of the greatest nights which appear on one of the odd nights of the last 10 nights of Ramadan - 21st, 23rd , 25th , 27th , 29th.
This one night is so valuable that there is a special surah in the Quran that devotes to it “Laylatul Qadr is better than a thousand months” [Surah Qadr]
Allah says in the Quran: Indeed We revealed it (the Holy Qura’an) on the night of Power. And what will make you know what the night of Power is, the night of Power is better than a thousand months, there in descends the Angels and the Rooh (Jibraeel Alayhis Salaam) with Allah’s permission with all decrees, Peace prevails till the rising of dawn.[Surah Qadr]
Let's try strive to stay up at least on the odd nights of the last ten days. If one prays on all of the last odd numbered nights then there is more chance that one may have caught this most powerful night. The reward of over 83 YEARS OF WORSHIP! Subhanallah! Most will not even live up to that age!
Dua for Laylatul Qadr:
Aisha (Ra) said: “I asked the Messenger of Allah: 'O Messenger of Allah, if I know what night is the night of Qadr, what should I say during it?' He said: 'Say: O Allah, You are pardoning and You love to pardon, so pardon me.' “

Gaining Forgiveness on Laylatul Qadr
Abu Huraira narrated that the Messenger said: “Whoever stands (in prayer) in Laylatul Qadr while nourishing his faith with self-evaluation, expecting reward from Allah, will have all of his previous sins forgiven.” (Bukhari and Muslim).
We should sincerely repent for past and present sins with the intention of not repeating them again and ask of Allah Ta’aala to help us prevent ourselves from doing them again and ask Allah to perfect our characters and to help us improve ourselves in everyway possible.
