The Kitáb-i-Aqdas (Arabic: The Most Holy Book) is the central religious text of the Baháʼí Faith, written by Baháʼu'lláh, the founder of the religion, in 1873. Though it is the main source of Baháʼí laws and practices, much of the content deals with other matters, like foundational principles of the religion, the establishment of Baháʼí institutions, mysticism, ethics, social principles, and prophecies. In Baha'i literature it is described as "the Mother-Book" of the Baháʼí teachings, and the "Charter of the future world civilization".Baháʼu'lláh had manuscript copies sent to Baháʼís in Iran some years after its writing in 1873, and in 1890–91 (1308 AH, 47 BE) he arranged for its first publication in Bombay, India. Parts of the text were translated to English by Shoghi Effendi, which, along with a Synopsis and Codification were published in 1973 by the Universal House of Justice at the centennial anniversary of its writing. The full authoritative English translation, along with clarifying texts from Baháʼu'lláh and detailed explanatory notes from the Universal House of Justice, was first published in 1992.
