The Tablets of Bahá’u’lláh Revealed After the Kitáb-i-Aqdas are selected tablets written by Bahá'u'lláh, the founder of the Bahá'í Faith, and published together as of 1978. As his mission drew to a close after his writing of the Kitáb-i-Aqdas in 1873, he continued to write unnumbered tablets and letters, doing so until the last days of his life in 1892.
