Obligatory Bahá'í prayers are prayers which are to be said daily by Bahá'ís according to a fixed form decreed by Bahá'u'lláh. Prayers in the Bahá'í Faith are reverent words which are addressed to God, and refers to two distinct concepts: obligatory prayer and devotional prayer (general prayer). The act of prayer is one of the most important Bahá'í laws for individual discipline.. Along with fasting, obligatory prayer is one of the greatest obligations of a Bahá'í, and the purpose of the obligatory prayer is to foster the development of humility and devotion. The obligation of daily obligatory prayer was prescribed by Bahá'u'lláh, the founder of the Bahá'í Faith, in his book of laws, the Kitáb-i-Aqdas.
