May 29th, 1892, at approximately 3 AM, marks the ascension of Bahá’u’lláh.The news of His ascension was instantly communicated to Sultan Abdu’l-Hamid 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.
For a full week a vast number of mourners, rich and poor alike, tarried to grieve with the bereaved family, partaking day and night of the food that was lavishly dispensed by its members. Notables, among whom were numbered Shi’ahs, Sunnis, Christians, Jews and Druzes, as well as poets, ulamas and government officials, all joined in lamenting the loss, and in magnifying the virtues and greatness of Bahá’u’lláh, many of them paying to Him their written tributes, in verse and in prose, in both Arabic and Turkish. From cities as far afield as Damascus, Aleppo, Beirut and Cairo similar tributes were received. These glowing testimonials were, without exception, submitted to His eldest Son, `Abdu’l-Bahá.
Already nine months before His ascension Baha’u’llah, as attested by `Abdu’l-Bahá, had voiced His desire to depart from this world. From that time onward it became increasingly evident, from the tone of His remarks to those who attained His presence, that the close of His earthly life was approaching, though He refrained from mentioning it openly to any one. On the night preceding the eleventh of Shavval 1309 A.H. (May 8, 1892) He contracted a slight fever which, though it mounted the following day, soon after subsided. He continued to grant interviews to certain of the friends and pilgrims, but it soon became evident that He was not well. His fever returned in a more acute form than before, His general condition grew steadily worse, complications ensued which at last culminated in His ascension, at the hour of dawn, on the 2nd of Dhi’l-Qa’dih 1309 A.H. (May 29, 1892), eight hours after sunset, in the 75th year of His age.
On this occasion, `Abdu’l-Bahá wrote:
The world’s great Light, once resplendent upon all mankind, hath set, to shine everlastingly from the Abhá Horizon, His Kingdom of fadeless glory, shedding splendour upon His loved ones from on high and breathing into their hearts and souls the breath of eternal life.
This day is one of the nine Bahá’i Holy Days, on which work is suspended.
