Domestic violence in Baha'u'llah's home.

With the backing of the Prime Minister and her powerful nephew, his last wife forced through the divorce with such a heavy settlement that he could not pay it immediately: so she had Bahá'u'lláh's father imprisoned in his own house, and set men to beat him daily and torture him to extract the money from him. At last, he was obliged to sell again his houses and furnishings in the capital for a negligible sum, leading to the separation of Bahá'u'lláh from His brother, who went to live near the entrance of a Mosque, whilst Bahá'u'lláh rented a place to live near the Gate of Shimiran, near the theological college where Mulla Husayn would stay on his journey, carrying the message of the Báb to Tihran.
