“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

October 18

This is the night [Birth of Baha’u’llah] round which have circled the Nights of Power, [Cf. Qur’án, súrih 97] wherein the angels and the Spirit have come down bearing cups filled at the streams of Paradise, the night wherein Heaven itself was adorned with the ornament of God, the Almighty, the All-Gracious, the Most Bountiful, wherein every created thing was brought to life, and all the peoples of the earth were surrounded by His grace. All joy to the concourse of the Spirit for this manifest and resplendent bounty! 
- Baha’u’llah  (Tablet of the Birth, ‘Days of Remembrance’)
