Its central figure was no less a person than the nominee of the Báb Himself, the credulous and cowardly Mírzá Yaḥyá, to certain traits of whose character reference has already been made in the foregoing pages. The black-hearted scoundrel who befooled and manipulated this vain and flaccid man with consummate skill and unyielding persistence was a certain Siyyid Muḥammad, a native of Iṣfáhán, notorious for his inordinate ambition, his blind obstinacy and uncontrollable jealousy. To him Bahá’u’lláh had later referred in the Kitáb-i-Aqdas as the one who had “led astray” Mírzá Yaḥyá, and stigmatized him, in one of His Tablets, as the “source of envy and the quintessence of mischief,” while ‘Abdu’l-Bahá had described the relationship existing between these two as that of “the sucking child” to the “much-prized breast” of its mother. Forced to abandon his studies in the madrisiyi-i-Sadr of Iṣfáhán, this Siyyid had migrated, in shame and remorse, to Karbilá, had there joined the ranks of the Báb’s followers, and shown, after His martyrdom, signs of vacillation which exposed the shallowness of his faith and the fundamental weakness of his convictions. Bahá’u’lláh’s first visit to Karbilá and the marks of undisguised reverence, love and admiration shown Him by some of the most distinguished among the former disciples and companions of Siyyid Kázim, had aroused in this calculating and unscrupulous schemer an envy, and bred in his soul an animosity, which the forbearance and patience shown him by Bahá’u’lláh had served only to inflame. His deluded helpers, willing tools of his diabolical designs, were the not inconsiderable number of Bábís who, baffled, disillusioned and leaderless, were already predisposed to be beguiled by him into pursuing a path diametrically opposed to the tenets and counsels of a departed Leader. For, with the Báb no longer in the midst of His followers; with His nominee, either seeking a safe hiding place in the mountains of Mázindarán, or wearing the disguise of a dervish or of an Arab wandering from town to town; with Bahá’u’lláh imprisoned and subsequently banished beyond the limits of His native country; with the flower of the Faith mown down in a seemingly unending series of slaughters, the remnants of that persecuted community were sunk in a distress that appalled and paralyzed them, that stifled their spirit, confused their minds and strained to the utmost their loyalty. Reduced to this extremity they could no longer rely on any voice that commanded sufficient authority to still their forebodings, resolve their problems, or prescribe to them their duties and obligations.
