Lailatul-Qadr `The Night of Power,` concealed in one of the odd nights in the last ten days of Ramadan; the night on which the Qur`an was first revealed by Jibraeel to the Prophet Muhammad (S.A.W.), and which the Qur`an itself describes as "better than a thousand months." See the Holy Qur`an, Al-Qadr (97:3).
