The month of Ramadhan has been singled out for special worship . It is a month unlike other months. One reason for this, as defined by the Qur’an, is because the Holy Qur’an was revealed in this month.
Laylat al-Qadr is to be found in the last five odd nights of the last third of Ramadan. While there is no specific date revealed in the Quran, Laylat al-Qadar is found to be on the last nights of Ramadan. Mostly it is on one of the odd nights: 21st, 23rd, 25th, 27th or 29th night. However there is inclination towards the night before the 27 of Ramadan.
Laylatul Qadr is a celebration of the arrival of the final word of God for humans. It is a tribute to the message revealed to mankind by their Creator, that was sent for the purpose of educating the means to achieve happiness in both the worlds.
We have indeed revealed this (Message) in the Night of Power:And what will explain to thee what the night of power is?The Night of Power is better than a thousand months.Therein come down the angels and the spirit by Allah’s permission, on every errand:Peace!…This until the rise of dawn!—Sura 97:1-5 (Al-Qadr)
Muslims are encouraged to stay awake the entire night praying, reading quran, and doing zhikr for blessings and forgiveness. Considering laylatul Qadr are the holiest nights of the year, it is wise to heed the tremendous benefits of the nights.
