Index term: Propriety
k51.
We have made it lawful for you to listen to music and singing. Take heed, however, lest listening thereto should cause you to overstep the bounds of propriety and dignity. Let your joy be the joy born of My Most Great Name, a Name that bringeth rapture to the heart, and filleth with ecstasy the minds of all who have drawn nigh unto God. We, verily, have made music as a ladder for your souls, a means whereby they may be lifted up unto the realm on high; make it not, therefore, as wings to self and passion. Truly, We are loath to see you numbered with the foolish.
k63.
God hath prescribed matrimony unto you. Beware that ye take not unto yourselves more wives than two. Whoso contenteth himself with a single partner from among the maidservants of God, both he and she shall live in tranquillity. And he who would take into his service a maid may do so with propriety. Such is the ordinance which, in truth and justice, hath been recorded by the Pen of Revelation. Enter into wedlock, O people, that ye may bring forth one who will make mention of Me amid My servants. This is My bidding unto you; hold fast to it as an assistance to yourselves.
k123.
Liberty must, in the end, lead to sedition, whose flames none can quench. Thus warneth you He Who is the Reckoner, the All-Knowing. Know ye that the embodiment of liberty and its symbol is the animal. That which beseemeth man is submission unto such restraints as will protect him from his own ignorance, and guard him against the harm of the mischief-maker. Liberty causeth man to overstep the bounds of propriety, and to infringe on the dignity of his station. It debaseth him to the level of extreme depravity and wickedness.
k145.
Take heed that ye enter no house in the absence of its owner, except with his permission. Comport yourselves with propriety under all conditions, and be not numbered with the wayward.
k159.
It hath been forbidden you to carry arms unless essential, and permitted you to attire yourselves in silk. The Lord hath relieved you, as a bounty on His part, of the restrictions that formerly applied to clothing and to the trim of the beard. He, verily, is the Ordainer, the Omniscient. Let there be naught in your demeanour of which sound and upright minds would disapprove, and make not yourselves the playthings of the ignorant. Well is it with him who hath adorned himself with the vesture of seemly conduct and a praiseworthy character. He is assuredly reckoned with those who aid their Lord through distinctive and outstanding deeds.

he who would take into his service a maid may do so with propriety
Bahá’u’lláh states that a man may employ a maiden for domestic service. This was not permissible under Shí­'ih Muslim practice unless the employer entered into a marriage contract with her. Bahá’u’lláh emphasizes that the “service” referred to in this verse is solely “such as is performed by any other class of servants, be they young or old, in exchange for wages” (Q&A 30). An employer has no sexual rights over his maid. She is “free to choose a husband at whatever time she pleaseth”, for the purchase of women is forbidden (Q&A 30).

The Lord hath relieved you . . . of the restrictions that formerly applied to clothing and to the trim of the beard.
Many rules about dress had their origins in the laws and traditional practices of the world’s religions. For example, the Shí­'ih clergy adopted for themselves a distinctive headdress and robes and, at one time, forbade the people to adopt European attire. Muslim practice, in its desire to emulate the custom of the Prophet, also introduced a number of restrictions with regard to the trim of the moustache and the length of the beard.
Bahá’u’lláh removed such limitations on one’s apparel and beard. He leaves such matters to the “discretion” of the individual, and at the same time calls upon the believers not to transgress the bounds of propriety and to exercise moderation in all that pertains to dress.

Question: Concerning the verse: "he who would take into his service a maid may do so with propriety."
Answer: This is solely for service such as is performed by any other class of servants, be they young or old, in exchange for wages; such a maiden is free to choose a husband at whatever time she pleaseth, for it is forbidden either that women should be purchased, or that a man should have more wives than two.
