Festival:Lailat al Qadr (27 Ramadan): The Night of Power
The festival of The Night of Power marks the night in which the Qur'an was first revealed to the Prophet Muhammad (pbuh) by Allah.
Muslims regard this as the most important event in history, and the Qur'an says that this night is better than a thousand months (97:3), and that on this night the angels descend to earth.
This is a festival that Muslims spend in study and prayer. Some will spend the whole night in prayer or in reciting the Qur'an.
Lailat al Qadr is a good time to ask for forgiveness. Allah's Apostle said... "Whoever establishes the prayers on the night of Qadr out of sincere faith and hoping to attain Allah's rewards (not to show off) then all his past sins will be forgiven."
(Bukhari Vol 1, Book 2: 34)
The date of 27 Ramadan for this day is a traditional date, as the Prophet Muhammad (pbuh) did not tell us when the Night of Power would be, although he suggested it was in the last 10 days of the month.
Because of this, many Muslims will treat the last 10 days of the month of Ramadan as a particularly good time for prayer and reading the Qur'an.
