Should anyone acquire one hundred mithqáls of gold, nineteen mithqáls thereof are God’s and to be rendered unto Him, the Fashioner of earth and heaven. Take heed, O people, lest ye deprive yourselves of so great a bounty. This We have commanded you, though We are well able to dispense with you and with all who are in the heavens and on earth; in it there are benefits and wisdoms beyond the ken of anyone but God, the Omniscient, the All-Informed. Say: By this means He hath desired to purify what ye possess and to enable you to draw nigh unto such stations as none can comprehend save those whom God hath willed. He, in truth, is the Beneficent, the Gracious, the Bountiful. 
(Baha’u’llah, ‘The Kitab-i-Aqdas’)
