Kitáb-i-Aqdas
The Kitáb-i-Aqdas (Persian: [keˈtɒːb e æɢdæs], lit. '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.
