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

A view of the interior of Baha'u'llah's room in the prison.
We have sustained the weight of all calamities to sanctify you from all earthly corruption and ye are yet indifferent.... We, verily, behold your actions. If We perceive from them the sweet smelling savor of purity and holiness, We will most certainly bless you. Then will the tongues of the inmates of Paradise utter your praise and magnify your names amidst them who have drawn nigh unto God. 

- Baha’u’llah  (Quoted by Shoghi Effendi in a letter dated 25 December 1938; ‘The Advent of Divine Justice’)
