The minimum amount subject to Huququ'lláh is reached when
one's possessions are worth the number of Vahid (19); that is, whenever one
owneth 19 mithqals of gold, or acquireth possessions attaining this value,
after having deducted therefrom the yearly expenses, the Huquq becometh
applicable and its payment is obligatory. - Baha’u’llah (The Compilation of Compilation,
vol. I, Huqúqu'lláh)
