The Kitáb-i-Aqdas - The Most Holy Book
Index term: Sable
k9.
Hair doth not invalidate your prayer, nor aught from which the spirit hath departed, such as bones and the like. Ye are free to wear the fur of the sable as ye would that of the beaver, the squirrel, and other animals; the prohibition of its use hath stemmed, not from the Qur'án, but from the misconceptions of the divines. He, verily, is the All-Glorious, the All-Knowing.

In some earlier religious Dispensations, the wearing of the hair of certain animals or having certain other objects on one's person was held to invalidate one's prayer. Bahá'u'lláh here confirms the Báb's pronouncement in the Arabic Bayán that such things do not invalidate one's prayer.
