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

December 13

Thou hast, O Chief, committed that which hath caused Muhammad, the Apostle of God, to lament in the most sublime Paradise. The world hath made thee proud, so much so that thou hast turned away from the Face through whose brightness the Concourse on high hath been illumined. Soon thou shalt find thyself in manifest loss! Thou didst conspire with the Persian Ambassador to harm Me, though I had come unto you from the source of majesty and grandeur with a Revelation that hath solaced the eyes of the favoured ones of God. 
- Baha’u’llah  (Súriy-i-Ra’ís, Tablet addressed to ‘Álí Páshá, the Ottoman Prime Minister, [referred to here as Ra’ís (Chief or Ruler)]; ‘The Summons of the Lord of Hosts’)
