Religion founded in the 19th century from a Muslim splinter group, Babism, by the Persian Baha'ullah. His message in essence was that all great religious leaders are manifestations of the unknowable God and all scriptures are sacred. There is no priesthood: all Baha'is are expected to teach, and to work towards world unification. There are about 4.5 million Baha'is worldwide. Great stress is laid on equality regardless of religion, race, or gender. Drugs and alcohol are forbidden, as is celibacy. Marriage is strongly encouraged; there is no arranged marriage, but parental approval must be given. Baha'is are expected to pray daily, but there is no set prayer. From 2 to 20 Mar, adults under 70 fast from sunrise to sunset. Administration is carried out by an elected body, the Universal House of Justice.
