Who was responsible for Baha'u'llah's sufferings (1) !?

Disregarding the reiterated injunctions of Baha'u'llah, seven of the exiles (Baha'is) decided to rid their community of its tormentors. They spoke to no one of their abominable plan. One night, when all was quiet in the town, they managed to enter the home of the adherents of Mirza Yahya and slew them. With Siyyid Muhammad and Aqa-Jan Big perished a recent recruit to their circle, Mirza Rida-Quliy-i-Tafrishi. This third victim had time and again broken his word, and all ties between him and the followers of Baha'u'llah had finally been severed.

Immediately pandemonium broke loose. The whole city was roused. People felt unsafe. Such were the fears of the populace that 'Abbud, whose house adjoined the residence of Baha'u'llah, added to the thickness of the walls separating the two houses.
