Obligation and Meaning

The Kitab-i-Aqdas, the book of laws Baha'u'llah revealed in 1873, prescribes fasting during the nineteen days of the month of Ala as one of the small number of obligations binding on every adult Baha'i in good health, alongside a daily obligatory prayer. From sunrise to sunset across the nineteen days, observant Baha'is abstain from food and drink, and the practice is read within the faith less as an act of self-denial for its own merit than as a discipline meant to loosen attachment to the material world and turn attention toward prayer and reflection. Baha'u'llah's own writings describe the fast as a fire that consumes heedlessness and a light that reveals the ardor of true devotion, language that keeps the emphasis on inward disposition rather than outward observance for its own sake.

The Aqdas exempts categories of people explicitly rather than leaving exemption to individual judgment: children below the age of maturity, the elderly, travelers, the sick, and women who are pregnant, nursing or menstruating are not required to fast, and those engaged in heavy physical labor may be excused or may make up missed days later, according to guidance the faith's institutions have issued since. The fast is universal across the worldwide Baha'i community and is not modified by local custom or national Spiritual Assembly discretion in the way some other observances are, since the Aqdas fixes both its dates and its exemptions directly.
