In Epistle to the Son of the Wolf (p174-176) Bahá'u'lláh mentions Mírzá 'Alí-Akbar, a relative of the Báb and Abu'l-Qásim-i-Káshí and states "several other suffered martyrdom through the decree pronounced by Mírzá Yahyá."

Since 1899, Bahá'í sacred texts had been hectographed and mimeographed by Mīrzā ʿAlī-Akbar Rūḥānī (known as Moḥebb-al-Solṭān) and others. Although the restrictive laws of the country prohibited the Bahá'ís from printing their literature by letterpress, through the establishment of the Trust, Bahá'í literature was regularly and systematically published in typewritten or calligraphic form until 1979 when the Trust was closed under the Islamic régime. Between 1959 and 1979, several hundred titles were produced and distributed. The trust was also responsible for the publication of circulars, newsletters, pamphlets, and magazines. In 1975 alone, it produced 181,390 copies of books and pamphlets totaling 31 million pages. In the early 1970s an audiovisual center was established in Iran which made rapid growth during the few years of its existence. In the mid-1970s the centre produced 27 cassette programs containing prayers, songs, and speeches amounting to 40,000 copies. They also produced 28 reels of film.
