…the Báb’s distinguished amanuensis, Siyyid Husayn-i-Yazdí,
surnamed Azíz, who had shared His confinement in both Máh-Kú and Chihríq.
A man of rich experience and high merit, deeply versed in the teachings of his
Master, and enjoying His unqualified confidence, he, refusing every offer of
deliverance from the leading officials of Tihrán, yearned unceasingly for the
martyrdom which had been denied him on the day the Báb had laid down His life
in the barrack-square of Tabríz. A fellow-prisoner of Bahá’u’lláh in the Síyáh-Chál
of Tihrán, from Whom he derived inspiration and solace as he recalled those
precious days spent in the company of his Master in Ádhirbayján, he was
finally struck down, in circumstances of shameful cruelty, by that same Azíz Khán-i-Sardár
who had dealt the fatal blow to Táhirih.
