Huququ’llah – “obedience to this Law is a matter of conscience” - 26 February 1973

…The devoted believer who is privileged to pay "the Right of God", far from seeking excuses for evading this spiritual obligation, will do his utmost to meet it. On the other hand, inasmuch as obedience to this Law is a matter of conscience, and payment of Huqúqu'lláh is a voluntary act, it would not be seemly to go beyond informing the Persian friends of their spiritual obligation, and leaving to them to decide what they wish to do about it.

The same principle applies to those friends who spend lavishly on their families, who purchase or build residences and furnish them far in excess of their needs, and rationalize these expenditures in their desire to avoid payment of Huqúqu'lláh. Likewise those friends who marry non-Persians and reside in Europe or other countries should not be pressed, but informed and left to decide for themselves.
