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

September 18

If thou attainest unto His [Baha’u’llah] Revelation, and obeyest Him, thou wilt have revealed the fruit of the Bayán; if not, thou art unworthy of mention before God. Take pity upon thyself. If thou aidest not Him Who is the Manifestation of the Lordship of God, be not, then, a cause of sadness unto Him.” And further He saith—magnified be His station: “If thou attainest not unto the Presence of God, grieve not, then, the Sign of God. Ye will renounce that which can profit them that acknowledge the Bayán, if ye renounce that which can harm Him. I know, however, that ye will refuse to do so. 
- The Báb  (Quoted by Baha’u’llah in the ‘Epistle to the Son of the Wolf’)
