When Baha'u'llah read Mulla Muhammad Baqir Majlisi he went into a state of acute depression for some time

Bahaullah had intimations of his prophetic calling while still a youth. He recounts an experience in his early years that changed his life, when he had read Mulla Muhammad Baqir Majlisi's (d. 1111A.H./ 1699C.E.) traditional account of the treachery of the Jewish tribe of Banu Qurayza, whose betrayal had placed the earliest Muslim community in mortal danger. On grounds of treason, the prophet Muhammad upheld a judge's order to punitively massacre all male members of that tribe (cf. Q. 33:26). MacEoin notes the impact of all this on the impressionable youth, writing that "the effect of this was to plunge him [Bahaullah] into a state of acute depression for some time, despite his recognition that 'what occurred had been the decree of God'" (MacEoin 1983, 223 on MA 7: 136; cf. ISH 34 and IQT 116ff). This characterization of the event truncates Bahaullah's own account of this psychological turning point.
