As to the Huqúq, 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 Huqúq hath once been paid, is exempt from Huqúq. This exemption also applieth to a property on which Huqúq hath already been paid, and the income of which doth not exceed one’s needs…. Disposition of the Huqúq, wholly or partly, is permissible, but this should be done by permission of the authority in the Cause to whom all must turn.
