Ḥuqúqu’lláh—The Right of God

As to the Ḥuqúq, it is payable on whatever is left over after deducting one’s yearly expenses. However, any money or possession which is necessary in producing income for one’s subsistence, and on which Ḥuqúq hath once been paid, is exempt from Ḥuqúq. This exemption also applieth to a property on which Ḥuqúq hath already been paid, and the income of which doth not exceed one’s needs…. Disposition of the Ḥuqúq, wholly or partly, is permissible, but this should be done by permission of the authority in the Cause to whom all must turn.
