Laylat al-Qadr — the Night of Power — commemorates the night during which the first verses of the Holy Qur’an were revealed to Prophet Muhammad (peace be upon him and his family). It is symbolic of the spiritual dimension of life, which for Muslims, gives meaning and purpose to their existence and holds the promise of a noble spiritual destiny.
On this night in 610 AD, the angel Jibril delivered the divine message from Allah to the Prophet, who had withdrawn for prayer in the cave of Hira. The Holy Qur’an describes Laylat al-Qadr in Surah 97:
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 morn!
Ismaili Muslims observe Laylat al-Qadr on the 23rd night of Ramadan, in accordance with traditions received through Hazrat Ali and Hazrat Bibi Fatima. It is a night of special prayer, reflection and remembrance of Allah.
