In the name of Allah, Most Gracious, Most Merciful.
1. Indeed, We sent it [i.e., the Quran] down during the Night of Decree[1].
2. And what can make you know what is the Night of Decree?
3. The Night of Decree is better than a thousand months[2].
4. The angels and the Spirit [i.e., Gabriel] descend therein by permission of their Lord for every matter[3].
5. Peace it is until the emergence of dawn.
Sura 97. Al-Qadr (The Night of Decree)
[1] Al-Qadr: Decree or Destiny. Other meanings are “precise measurement [i.e., amount or extent],” “value,” “gravity” or “greatness.”
[2] a thousand months: worshipping Allah in that night is better than worshipping Allah a thousand months, i.e. 83 years and 4 months.
[3] They bring down the decree for everything destined to occur in the coming year.
