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

April 9

This is the day which God hath announced through the tongue of His Apostle. [Muhammad] …This is the day whereon He Who is the Dayspring of Revelation hath come with clear tokens which none can number. This is the day whereon every man endued with perception hath discovered the fragrance of the breeze of the All-Merciful in the world of creation, and every man of insight hath hastened unto the living waters of the mercy of his Lord, the King of Kings. 
- Baha’u’llah  (‘Epistle to the Son of the Wolf’)
