Index term: of House of Justice, under Authority
k42.
Endowments dedicated to charity revert to God, the Revealer of Signs. None hath the right to dispose of them without leave from Him Who is the Dawning-place of Revelation. After Him, this authority shall pass to the Aghsán, and after them to the House of Justice -- should it be established in the world by then -- that they may use these endowments for the benefit of the Places which have been exalted in this Cause, and for whatsoever hath been enjoined upon them by Him Who is the God of might and power. Otherwise, the endowments shall revert to the people of Bahá who speak not except by His leave and judge not save in accordance with what God hath decreed in this Tablet -- lo, they are the champions of victory betwixt heaven and earth -- that they may use them in the manner that hath been laid down in the Book by God, the Mighty, the Bountiful.

Whoso wisheth to increase this sum, it is forbidden him to exceed the limit of ninety-five mithqáls . . . If he content himself, however, with a payment of the lowest level, it shall be better for him according to the Book.
In answer to a question about the dowry, Bahá'u'lláh stated:

Whatever is revealed in the Bayán, in respect to those residing in cities and villages, is approved and should be carried out. However, in the Kitáb-i-Aqdas mention is made of the lowest level. The intention is nineteen mithqáls of silver, specified in the Bayán for village-dwellers. This is more pleasing unto God, provided the two parties agree. The purpose is to promote the comfort of all, and to bring about concord and union among the people. Therefore, the greater the consideration shown in these matters the better it will be . . . The people of Bahá must associate and deal with each other with the utmost love and sincerity. They should be mindful of the interests of all, especially the friends of God.

'Abdu'l-Bahá, in one of His Tablets, summarized some of the provisions for determining the level of the dowry. The unit of payment mentioned in the extract, cited below, is the "váhid". One váhid is equivalent to nineteen mithqáls. He stated:

City-dwellers must pay in gold and village-dwellers in silver. It dependeth on the financial means at the disposal of the groom. If he is poor, he payeth one váhid; if of modest means, he payeth two váhids; if well-to-do, three váhids; if wealthy, four váhids; and if very rich, he giveth five váhids. It is, in truth, a matter for agreement between the bridegroom, the bride, and their parents. Whatever agreement is reached should be carried out.

In this same Tablet, 'Abdu'l-Bahá encouraged the believers to refer questions concerning the application of this law to the Universal House of Justice, which has "the authority to legislate". He stressed that "it is this body which will enact laws and legislate upon secondary matters which are not explicit in the Holy Text".
