Say: O people, the first duty is to recognize the one true
God -- magnified be his Glory -- the second is to show forth constancy in His
Cause and, after these, one's duty is to purify one's riches and earthly
possessions according to that which is prescribed by God. Therefore it
beseemeth thee to meet thine obligation to the Right of God first, then to
direct thy steps toward His blessed House. This hath been brought to thine
attention as a sign of favour.
- Baha’u’llah (The Compilation of Compilation,
vol. I, Huqúqu'lláh)
