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). 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!"
Shia 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.
