Language of Origin: Farsi (Persian)
The Persian Bayán was written while the Báb was imprisoned in Maku. The book contains elements of Bábí law, discussion of religious concepts, and the glorification of "He whom God shall make manifest." It was one of the Báb's first works in which he clearly states that he is the messianic figure of the Twelfth Imam and the Mahdi which the Shi'as were expecting. With the claim, he also claimed the abrogation of the Islamic dispensation, and uses the new Bábí law to abrogate Islamic law. Shoghi Effendi considered it a "eulogy of the Promised One", who had abrogated the laws of Islam, and prophesied about the coming of the Bahá'í Faith.
