God hath enjoined upon you to observe the utmost
cleanliness, to the extent of washing what is soiled with dust, let alone with
hardened dirt and similar defilement. Fear Him, and be of those who are pure.
Should the garb of anyone be visibly sullied, his prayers shall not ascend to
God, and the celestial Concourse will turn away from him. Make use of
rose-water, and of pure perfume; this, indeed, is that which God hath loved
from the beginning that hath no beginning, in order that there may be diffused
from you what your Lord, the Incomparable, the All-Wise, desireth.
(Baha’u’llah,
‘The Kitab-i-Aqdas’)
