It was during His incarceration in the fortress of Máh-Kú that He, according to the testimony of Shaykh 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.
