This work, of such exalted merit, of such far-reaching influence, was followed by the revelation of the Báb’s first Tablet to Muḥammad _Sh_áh; of His Tablets to Sulṭán ‘Abdu’l-Majíd and to Najíb Pá_sh_á, the Valí of Ba_gh_dád; of the Sahífiy-i-baynu’l-Harámayn, revealed between Mecca and Medina, in answer to questions posed by Mírzá Muhít-i-Kirmání; of the Epistle to the _Sh_eríf of Mecca; of the Kitábú’r-Rúh, comprising seven hundred súrihs; of the _Kh_asá’il-i-Sab‘ih, which enjoined the alteration of the formula of the a_dh_án; of the Risáliy-i-Furú-i-‘Adlíyyih, rendered into Persian by Mullá Muḥammad-Taqíy-i-Haratí; of the commentary on the súrih of Kaw_th_ar, which effected such a transformation in the soul of Vahíd; of the commentary on the súrih of Va’l-‘Asr, in the house of the Imám-Jum’ih of Iṣfáhán; of the dissertation on the Specific Mission of Muḥammad, written at the request of Manú_ch_ihr _Kh_án; of the second Tablet to Muḥammad _Sh_áh, craving an audience in which to set forth the truths of the new Revelation, and dissipate his doubts; and of the Tablets sent from the village of Síyáh-Dihán to the ‘ulamás of Qazvín and to Ḥájí Mírzá Aqásí, inquiring from him as to the cause of the sudden change in his decision. The great bulk of the writings emanating from the Báb’s prolific mind was, however, reserved for the period of His confinement in Máh-Kú and _Ch_ihríq. To this period must probably belong the unnumbered Epistles which, as attested by no less an authority than Bahá’u’lláh, the Báb specifically addressed to the divines of every city in Persia, as well as to those residing in Najaf and Karbilá, wherein He set forth in detail the errors committed by each one of them. It was during His incarceration in the fortress of Máh-Kú that He, according to the testimony of _Sh_ay_kh_ Ḥasan-i-Zunúzí, who transcribed during those nine months the verses dictated by the Báb to His amanuensis, revealed no less than nine commentaries on the whole of the Qur’án—commentaries whose fate, alas, is unknown, and one of which, at least the Author Himself affirmed, surpassed in some respects a book as deservedly famous as the Qayyúmu’l-Asmá.
