Whoso is privileged to pay the Right of God will be numbered with such as have observed the ordinances of the one true God -- magnified be His glory -- and have fulfilled that which is set down by the All-Glorious Pen.
Time and again have We written and commanded that no one should solicit such payment. The offering of every person that voluntarily tendereth the Huququ'lláh with the utmost joy and pleasure may be accepted, otherwise acceptance was not and is not permissible. Those that are oblivious of their duty should be briefly reminded. Deeds must be performed with willingness and in all circumstances high regard must be given to the dignity of the Cause of God. Formerly We have mentioned that were a person to possess the whole world and would tender his possessions at the cost of degrading the honour of the Cause, even to the extent of a grain of mustard, it would be essential and imperative to refuse to accept such wealth. Such is the Cause of God, eternal in the past, eternal in the future. Well is it with them that act accordingly.
- Baha’u’llah (The Compilation of Compilation, vol. I, Huqúqu'lláh)
