The enormous expansion in the scope and volume of Bahá’u’lláh’s writings, after His return from Sulaymáníyyih, is yet another distinguishing feature of the period under review. The verses that streamed during those years from His pen, described as “a copious rain” by Himself, whether in the form of epistles, exhortations, commentaries, apologies, dissertations, prophecies, prayers, odes or specific Tablets, contributed, to a marked degree, to the reformation and progressive unfoldment of the Bábí community, to the broadening of its outlook, to the expansion of its activities and to the enlightenment of the minds of its members. So prolific was this period, that during the first two years after His return from His retirement, according to the testimony of Nabíl, who was at that time living in Ba_gh_dád, the unrecorded verses that streamed from His lips averaged, in a single day and night, the equivalent of the Qur’án! As to those verses which He either dictated or wrote Himself, their number was no less remarkable than either the wealth of material they contained, or the diversity of subjects to which they referred. A vast, and indeed the greater, proportion of these writings were, alas, lost irretrievably to posterity. No less an authority than Mírzá Áqá Ján, Bahá’u’lláh’s amanuensis, affirms, as reported by Nabíl, that by the express order of Bahá’u’lláh, hundreds of thousands of verses, mostly written by His own hand, were obliterated and cast into the river. “Finding me reluctant to execute His orders,” Mírzá Áqá Ján has related to Nabíl, “Bahá’u’lláh would reassure me saying: ‘None is to be found at this time worthy to hear these melodies.’ ...Not once, or twice, but innumerable times, was I commanded to repeat this act.” A certain Muḥammad Karím, a native of _Sh_íráz, who had been a witness to the rapidity and the manner in which the Báb had penned the verses with which He was inspired, has left the following testimony to posterity, after attaining, during those days, the presence of Bahá’u’lláh, and beholding with his own eyes what he himself had considered to be the only proof of the mission of the Promised One: “I bear witness that the verses revealed by Bahá’u’lláh were superior, in the rapidity with which they were penned, in the ease with which they flowed, in their lucidity, their profundity and sweetness to those which I, myself saw pour from the pen of the Báb when in His presence. Had Bahá’u’lláh no other claim to greatness, this were sufficient, in the eyes of the world and its people, that He produced such verses as have streamed this day from His pen.”
