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

May 18

They [Bábis] that have turned aside from Me have spoken even as the followers of John (the Baptist) spoke. For they, too, protested against Him Who was the Spirit (Jesus) saying: “The dispensation of John hath not yet ended; wherefore hast thou come?” Now, too, they that have repudiated Us, though they have never known Us and have been at all times ignorant of the fundamentals of this Cause, knowing not from Whom it proceeded or what it signifieth, have spoken that which hath made all created things to sigh and lament. By My life! The mute can never confront the One Who incarnateth in Himself the kingdom of utterance. Fear God, O people, and peruse, then, that which hath been sent down with truth in the eighth Chapter of the sixth Vahíd of the Bayán, and be not of such as have turned aside. He, likewise, hath commanded: “Once every nineteen days this Chapter should be read, that haply they may not be veiled, in the time of the revelation of Him Whom God shall make manifest, by considerations foreign to the verses, which have been, and are still, the weightiest of all proofs and testimonies.” 
- Baha’u’llah  (‘Epistle to the Son of the Wolf’)
