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

February 18

We make mention of thee[Queen Victoria] for the sake of God, and desire that thy name may be exalted through thy remembrance of God, the Creator of earth and of heaven. He, verily, is witness unto that which I say. We have been informed that thou hast forbidden the trading in slaves, both men and women. This, verily, is what God hath enjoined in this wondrous Revelation. God hath, truly, destined a reward for thee, because of this. He, verily, will pay the doer of good, whether man or woman, his due recompense, wert thou to follow what hath been sent unto thee by Him Who is the All-Knowing, the All-Informed. As to him who turneth aside, and swelleth with pride, after that the clear tokens have come unto him, from the Revealer of signs, his work shall God bring to naught. He, in truth, hath power over all things. Man’s actions are acceptable after his having recognized (the Manifestation). He that turneth aside from the True One is indeed the most veiled amongst His creatures. Thus hath it been decreed by Him Who is the Almighty, the Most Powerful. 
(Baha’u’llah, from a Tablet addressed to Queen Victoria, quoted by Baha’u’llah in the ‘Epistle to the Son of the Wolf’)
