In Bábism, a Bayán (Arabic: بیان), or exposition, denotes the whole body of the works of the Báb, the central one being the Persian Bayán. Some modern Bábís (followers of the Báb) call themselves 'Bayaní' after this title of the Báb's writings. Bahá'ís also see this work as holy, since they consider their founder to be the fulfillment of the Báb's main prophetic anticipation.
