He [Nabil] entered the presence of Bahá’u’lláh in Kirmansháh
and Tihrán before the date of the exile to ‘Iráq, and afterwards was in
attendance upon Him in Baghdád and Adrianople as well as in the prison-city of
Akká. He was sent more than once on missions to Persia to promote the Cause and
to encourage the scattered and persecuted believers, and he was living in Akká when
Bahá’u’lláh passed away in 1892 A.D. The manner of his death was pathetic and
lamentable, for he became so dreadfully affected by the death of the Great
Beloved that, overmastered by grief, he drowned himself in the sea, and his
dead body was found washed ashore near the city of Akká.
