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

May 17

Alas, alas, for the things which have befallen Me! By God! There befell Me at the hands of him whom I have nurtured (Mírzá Yaḥyá), by day and by night, what hath caused the Holy Spirit, and the dwellers of the Tabernacle of the Grandeur of God, the Lord of this wondrous Day, to lament. 
- Baha’u’llah  (‘Epistle to the Son of the Wolf’)
