Laylatu l-Qadr is the night the Qur’ān descended from Lawḥu l-Maḥfūẓ. It occurs one night of the year but which night is a secret. Usually it is in the last 10 nights of Ramaḍān, often the 27th night. The Prophet (sas) said it is good to be awake and praying this night and to ask for forgiveness and for health.
