A leading disciple of Siyyid Kázim suffered imprisonment in Tihrán, in the same dungeon within which Bahá’u’lláh was confined

This same Shaykh Abú-Turáb, [a leading disciple of Siyyid Kázim] who in the early days of the Dispensation proclaimed by the Báb thought it wiser and better not to identify himself with His Cause, cherished in his heart the fondest love for the revealed Manifestation, and in his faith remained firm and immovable as the rock. Eventually that smouldering fire blazed forth in his soul and was responsible for such behaviour on his part as to cause him to suffer imprisonment in Tihrán, in the same dungeon within which Bahá’u’lláh was confined. He remained steadfast to the very end, and crowned a life of loving sacrifice with the glory of martyrdom.
