May 29

The news of His [Baha’u’llah’s] ascension was instantly communicated to Sultán ‘Abdu’l-Hamíd in a telegram which began with the words “the Sun of Bahá has set” and in which the monarch was advised of the intention of interring the sacred remains within the precincts of the Mansion, an arrangement to which he readily assented. Bahá’u’lláh was accordingly laid to rest in the northernmost room of the house which served as a dwelling-place for His son-in-law, the most northerly of the three houses lying to the west of, and adjacent to, the Mansion. His interment took place shortly after sunset, on the very day of His ascension.
