Baha'u'llah's sister Khānum Buzurg describes the terrorist activities of earlier Baha'is

Baha'i Terrorists according to Baha'u'llah's own sister.

“They gathered a group of hooligans from different provinces of Iran and from the same places fugitives who had never believed in any religion and had no faith in any prophet and had no work but manslaughter and had no occupation but stealing peoples’ property. Even though they claimed they were following [the customs] of Ḥusayn (the grandson of the Prophet Muḥammad who was ruthlessly murdered by Shimr on the orders of Yazīd) they summoned a group of Shimr-like people around themselves. The breath of any soul who uttered anything but what they were satisfied with was suffocated. They beat any head which made the slightest sound other than accepting their guardianship. They cut every throat which showed other than humbleness towards them. They pierced every heart which had love towards other than them. The first group whose names we previously mentioned fled to Karbala, Najaf and elsewhere fearing those bloodthirsty headsmen. They beheaded Sayyid Ismā`īl Iṣfahānī, they ripped Mīrzā Aḥmad Kāshī’s guts, they killed Āghā Abul-Qāsim Kāshi and threw his body in the Tigris river, they finished Sayyid Aḥmad with a gun, they scattered Mīrzā Ridhā’s brain with rocks, they cut Mīrzā `Alī’s body from the sides and pushed him unto the path of demise. Other than these, they killed others in the darkness of night and threw their bodies in the Tigris river; yet others were killed in the Bazaar in daylight and cut to pieces with daggers and machetes . . .,” `Izziyyih Khānum (Khānum Buzurg), Tanbīh al-nā’imīn, pp. 11–12.
