In the name of God, the Benevolent, the Merciful.
1 Lo! We revealed it on the Night of Predestination.
2 Ah, what will convey unto thee what the Night of Power is!
3 The Night of Power has more blessings than a thousand months.
4 The angels and the Spirit descend therein, by the permission of their Lord, with all decrees.
5 (The night is) Peace until the rising of the dawn.
The verses above regard the Night as better than one thousand months. The whole month of Ramadan is a period of spiritual training wherein believers devote much of their time to fasting, praying, reciting the Qur'an, remembering God, and giving charity. However because of the revealed importance of this night, Muslims strive harder in the last ten days of Ramadan since the Laylat al-Qadr could be one of the odd-numbered days in these last ten (the first, third, fifth, or seventh). Normally, some Muslims from each community would perform an i'tikaf in the mosque: they remain in the mosque for the last ten days of the month for prayers and recitation.
It is recommended to supplicate a great deal in it, it is reported from 'Aa'ishah, RA that she said: "O Messenger of Allaah! What if I knew which night Lailatul-Qadr was, then what should I say in it?" He said: "Say: Allaahumma innaka 'affuwwun tuhibbul 'afwa fa'fu 'annee." (O Allaah you are the one who pardons greatly, and loves to pardon, so pardon me.) (at-Tirmidhi, Ibn Majah)
