Indeed, We sent the Qur’an down during the Night of Decree And what can make you know what is the Night of Decree? The Night of Decree is better than a thousand months. The angels and the Spirit descend therein by permission of their Lord for every matter. Peace it is until the emergence of dawn. Qur’an | 97:1-5
