Some of His disciples the Báb assiduously prepared to expect the imminent Revelation. Others He orally assured would live to see its day. To Mullá Báqir, one of the Letters of the Living, He actually prophesied, in a Tablet addressed to him, that he would meet the Promised One face to face. To Sáyyah, another disciple, He gave verbally a similar assurance. Mullá Ḥusayn He directed to Ṭihrán, assuring him that in that city was enshrined a Mystery Whose light neither Ḥijáz nor _Sh_íráz could rival. Quddús, on the eve of his final separation from Him, was promised that he would attain the presence of the One Who was the sole Object of their adoration and love. To _Sh_ay_kh_ Ḥasan-i-Zunúzí He declared while in Máh-Kú that he would behold in Karbilá the countenance of the promised Ḥusayn. On Dayyán He conferred the title of “the third Letter to believe in Him Whom God shall make manifest,” while to Aẓím He divulged, in the Kitáb-i-Panj-_Sh_a’n, the name, and announced the approaching advent, of Him Who was to consummate His own Revelation. A successor or vicegerent the Báb never named, an interpreter of His teachings He refrained from appointing. So transparently clear were His references to the Promised One, so brief was to be the duration of His own Dispensation, that neither the one nor the other was deemed necessary. All He did was, according to the testimony of ‘Abdu’l-Bahá in “A Traveller’s Narrative,” to nominate, on the advice of Bahá’u’lláh and of another disciple, Mírzá Yaḥyá, who would act solely as a figure-head pending the manifestation of the Promised One, thus enabling Bahá’u’lláh to promote, in relative security, the Cause so dear to His heart.
