October 25. On this date in 1970, the Universal House of Justice wrote the National Spiritual Assembly of Iran that "Payment of Huququ'llah is a spiritual obligation binding on the people of Baha. The injunction is laid down in the Most Holy Book, and clear and conclusive explanations are embodied in various Tablets. Every devoted believer who is able to meet the specified conditions, must pay the Huququ'llah, without any exception. Indeed according to the explicit Text of the Most Holy Book, failure to comply with this injunction is regarded as a betrayal of trust, and the divine call: 'Whoso dealeth dishonestly with God will in justice be exposed,' is a clear reference to such people."

1044. Payment of the Huququ'llah is a Binding Spiritual Obligation--Conduces to Prosperity and Honour, Ensures Attainment of True Happiness
"Payment of Huququ'llah is a spiritual obligation binding on the people of Baha. The injunction is laid down in the Most Holy Book, and clear and conclusive explanations are embodied in various Tablets.
"Every devoted believer who is able to meet the specified conditions, must pay the Huququ'llah, without any exception. Indeed according to the explicit Text of the Most Holy Book, failure to comply with this injunction is regarded as a betrayal of trust, and the divine call: 'Whoso dealeth dishonestly with God will in justice be exposed,' is a clear reference to such people.
"The Centre of the Covenant has affirmed the obligation of Huquq in these words: 'The Lord as a sign of His infinite bounties hath graciously favoured His servants by providing for a fixed money offering (Huquq), to be dutifully presented unto Him, though He, the True One and His servants have been at all times independent of all created things'.
"This weighty ordinance, as testified by the Pen of Glory is invested with incalculable benefit and wisdom. It purifies one's possessions, averts loss and disaster, conduces to prosperity and honour and imparts divine increase and blessing. It is a sacrifice offered for and related to God, and an act of servitude leading to the promotion of His Cause. As affirmed by the Centre of the Covenant, Huquq offerings constitute a test for the believers and enable the friends to become firm and steadfast in faith and certitude.
"In brief, payment of Huququ'llah is one of the binding spiritual responsibilities of the followers of Bahá'u'lláh and the proceeds thereof revert to the Authority in the Cause to whom all must turn. Moreover, the Ancient Beauty--magnified be His praise--has affirmed that after the establishment of the Universal House of Justice necessary rulings would be enacted in this connection in conformity with that which God has purposed, and that no one, except the Authority to which all must turn, has the right to dispose of this Fund. In other words, whatever portion of one's wealth is due to the Huququ'llah belongs to the World Centre of the Cause of God, not to the individuals concerned.
"Thus the friends should not follow their own volition and judgement in using any of the funds set aside for Huququ'llah for any other purpose, even for charitable contributions of the Faith.
"We earnestly hope that everyone may be privileged to observe this sacred and blessed obligation which would ensure the attainment of true happiness and would serve to promote the execution of Bahá'í enterprises throughout the world.
"Verily God is Self-Sufficient above the need of His creatures."
