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

July 3

All feasts have attained their consummation in the two Most Great Festivals, and in two other Festivals that fall on the twin days—the first of the Most Great Festivals being those days whereon God shed the effulgent glory of His most excellent Names upon all who are in heaven and on earth, and the second being that day on which We raised up the One Who announced unto the people the glad tidings of this Great Announcement. [1]   Thus hath it been set down in the Book by Him Who is the Mighty, the Powerful.  On other than these four consummate days, engage ye in your daily occupations, and withhold yourselves not from the pursuit of your trades and crafts.  Thus hath the command been issued and the law gone forth from Him Who is your Lord, the All-Knowing, the All-Wise. 
- Baha'u'llah  (Tablet to Napoleon III, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
[1] The two Most Great Festivals are the Festival of Riḍván, during which Bahá’u’lláh first proclaimed His Mission, and the Declaration of the Báb.  The “twin days” refer to the Birthdays of the Báb and Bahá’u’lláh.
