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

September 24

…in every subsequent Revelation, the return of the former Revelation is a fact, the truth of which is firmly established. Inasmuch as the return of the Prophets of God, as attested by verses and traditions, hath been conclusively demonstrated, the return of their chosen ones also is therefore definitely proven. This return is too manifest in itself to require any evidence or proof. 
- Baha’u’llah  (‘The Kitab-i-Iqan’)
