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 Chihríq. 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.
