Baháʼu'lláh wrote down the law of Huqúqu'lláh in the Kitáb-i-Aqdas in 1873, but he did not accept any payments initially. He delayed the release of the "Kitáb-i-Aqdas" because of apprehension that the law of Huqúq might be difficult to implement, or that some would assume that the money was for his personal use. When copies were sent to Iran, they came with instructions that Huqúqu'lláh was not to be implemented, and it remained thus for about 5 years, during which time Baháʼu'lláh returned money to donors. In 1878 he appointed the first trustee of Huqúqu'lláh, who had the responsibility of receiving the "Huqúq", as it is known, from the Baháʼís in Iran. The majority of these donations were spent caring for the poor and needy of the community, or for teaching efforts. Baháʼu'lláh and his family led an austere life.
