"The Kitáb-i-Aqdas" by Baháʼu'lláh is a religious text written in 1873. Regarded as the central scripture of the Baháʼí Faith, this work establishes laws and foundational principles for a new religion. Written in Arabic while Baháʼu'lláh was in Acre, the book addresses prayer, fasting, marriage, and inheritance, while also outlining future religious institutions and social principles. Described as "the Mother-Book" and "Charter of the Future World Civilization," it presents its teachings through short principles rather than narrative, offering guidance for both individual conduct and collective organization.
