The Kitáb-i-Aqdas
106.God hath … abolished the concept of “uncleanness,” whereby divers things and peoples have been held to be impure.   ¶75
The concept of ritual “uncleanness,” as understood and practised in some tribal societies and in the religious communities of certain earlier Dispensations, has been abolished by Bahá’u’lláh. He states that through His Revelation “all created things were immersed in the sea of purification.” (See also notes 12, 20, and 103.)
