…if a believer has calculated his liability to Huqúqu’lláh and knows that he owes some, he should pay this in preference to making any other contributions.

However, during the course of the year a believer may well be making contributions to various funds, or giving money to charity, just as he is spending his money on a wide range of activities associated with his daily life. The … Universal House of Justice leaves it to his judgement to follow either of the following courses:

(a) To treat such contributions as expenses. They would then reduce the balance of savings he would have left at the end of the year on which Huqúqu’lláh is payable.

(b) To consider that he should make such contributions only out of money on which Huqúqu’lláh has been paid. 20

This ruling also leaves it open to the individual to treat some contributions in one way and some in the other. The House of Justice leaves all such details to the judgement and conscience of the individual believer.
