The Kitab-i-aqdas, or “Most Holy Book,” is regarded as the central document of the Baha'i faith. It was written by Baha'u'llah, or Baha' Allah (born Mirza Hoseyn 'Ali Nuri), whom Baha'is regard as the most recent “manifestation of God” and the founder of the religion that will unify all races and all religions. While the exact dates of the book's composition are unknown, scholars and Baha'is agree that the text was completed around 1873, though some of it may have been written significantly earlier, perhaps as early as 1868. Tradition states that the text was completed while Baha'u'llah lived in the Mansion of Bahji in Acre, Israel, which was also the site of his death in 1892.
