His name was mentioned in many Tablets of Bahá'u'lláh, consoling his family. His son was appointed caretaker of the pilgrims in 'Akká and he served in this capacity until the days of Shoghi Effendi. [FAA8]

In it the urges him to live a pious life, to cleanse his heart from the defilement of the world, and to become detached from his own self and all created things. Bahá'u'lláh extols His own Essence, and states that for many years He had revealed the Words of God in great profusion while hiding His glory behind many veils of concealment. When the appointed hour had struck, however, He unveiled His exalted station and shed an infinitesimal measure of the light of His countenance upon all created things. As a result of this outpouring, the Concourse on high and the chosen ones of God were awestruck and dumbfounded. [RoB2p274]

• See 'Abdu'l-Bahá's Response to the Doctrine of the Unity of Existence by Keven Brown Fourth Section.
• See as well BNE52. Here, 'Abdu'l-Bahá is described as "about fifteen or sixteen years of age".
• Mention of this Tablet is made in Messages to Canada, p34-35, where, in a letter written on behalf of Shoghi Effendi, it is stated that the Tablet is about 50 pages in length and had been published in 'Abdu'l-Bahá's second volume of His Tablets published in Egypt.
• A Tablet of Baháʼuʼlláh, recently discovered by Necati Alkan and available in provisional translation by Adib Masumian, indicates that it was written during the sojourn in Edirne. The original text has been published in Safíniy-i-ʻIrfán, vol. 6, p. 10 (2003). In the Tablet Bahá'u'lláh says that Ali (Şevket/Shawkat) Pasha requested 'Abdu'l-Bahá to write His commentary "during the days of stopover/residence in the Land of Mystery" (dar ayyám-i tavaqquf dar Ard-i Sirr).

  And now concerning the extensive commentary on the Islamic tradition which begins, "I was a hidden treasure…" During the days of Our sojourn in the Land of Mystery, ʻAlí Páshá had asked the Most Mighty Branch of God—may My life be a sacrifice for the ground which His most pure footsteps have trodden—to provide a commentary on this hadith. This He did in accordance with the exigencies of the time, and His purpose was that all may benefit from it…

  As per a 1995 article prepared for The Bahá'í Encyclopedia, it was previously believed that 'Abdu'l-Bahá was 17 years old at the time of writing, if so, this would have dated the Tablet at about 1861. Given that this new evidence proves that it was written in Edirne, He would have been 19 years old but more probably in his early twenties.
