Bahá’u’lláh confirms the injunction in the Arabic Bayán regarding the renewal, every nineteen years, of the furnishings of one’s home, provided one is able to do so. ‘Abdu’l-Bahá relates this ordinance to the promotion of refinement and cleanliness. He explains that the purpose of the law is that one should change those furnishings that become old, lose their lustre and provoke repugnance. It does not apply to such things as rare or treasured articles, antiques or jewellery. 167. Wash your feet #152 The believers are exhorted in the Kitáb-i-Aqdas to bathe regularly, to wear clean clothes and generally to be the essence of cleanliness and refinement. The Synopsis and Codification, section IV.D.3.y.i.-vii., summarizes the relevant provisions. In relation to the washing of the feet, Bahá’u’lláh states that it is preferable to use warm water; however, washing in cold water is also permissible (Q and A 97). 168. Ye have been prohibited from making use of pulpits. Whoso wisheth to recite unto you the verses of his Lord, let him sit on a chair placed upon a dais #154 These provisions have their antecedent in the Persian Bayán. The Báb forbade the use of pulpits for the delivery of sermons and the reading of the Text. He specified, instead, that to enable all to hear the Word of God clearly, a chair for the speaker should be placed upon a platform. In comments on this law, ‘Abdu’l-Bahá and Shoghi Effendi have made it clear that in the Mas̱ẖriqu’l-Aḏẖkár (where sermons are prohibited and only the words of Holy Scripture may be read) the reader may stand or sit, and if necessary to be better heard, may use a low moveable platform, but that no pulpit is permitted. In the case of meetings in places other than the Mas̱ẖriqu’l-Aḏẖkár, it is also permissible for the reader or speaker to sit or stand, and to use a platform. In one of His Tablets, when reiterating the prohibition of the use of pulpits in any location, ‘Abdu’l-Bahá has stressed that when Bahá’ís deliver their speeches in gatherings, they are to do so in an attitude of utmost humility and self-abnegation. 169. Gambling #155 The activities that are included in this prohibition have not been outlined in the Writings of Bahá’u’lláh. As both ‘Abdu’l-Bahá and Shoghi Effendi have indicated, it is left to the Universal House of Justice to specify the details of this prohibition. In response to questions about whether lotteries, betting on such things as horse races and football games, bingo, and the like, are included under the prohibition of gambling, the Universal House of Justice has indicated that this is a matter that will be considered in detail in the future. In the meantime, the Assemblies and individuals are counselled not to make an issue of these matters and to leave it to the conscience of the individual believers. The House of Justice has ruled that it is not appropriate for funds for the Faith to be raised through lotteries, raffles, and games of chance.
