Bahá'u'lláh's imprisonment
After an attempt on the Shah's life by two Bábís in 1852, Bahá'u'lláh is held for four months in the Síyáh-Chál, the Black Pit of Tehran. Bahá'ís understand this imprisonment as the moment of his intimation of revelation, the vision of the Maid of Heaven recorded in his own writings.
