The 18th and last of the “Letters of the Living” comprising the original disciples of the the faith’s founding prophet the Bab, Quddus was a charismatic young mullah of whom it was said that “whoever was intimately associated with him was seized with an insatiable admiration for the charm of the youth.” Denis MacEoin even argues that Quddus’s preaching verged on asserting divinity, and he might have been an incipient rival to the Bab himself for leadership of the new religion.
Under either leader the movement was officially excommunicate to the ulama, and its heretical proselytizing consequently generated no shortage of martyr-making backlash. The backlash in question for this post began with an anti-Baha’i riot in the Mazandaran city of Barfurush (today, Babol) which drove a few hundred adherents to the nearby Shrine of Shaykh Tabarsi where they took refuge behind ad hoc defensive fortifications.
The Persians’ ensuing besiegement of this redoubt constitutes the Battle of Fort Tabarsi — and if the designation sounds a bit exalted for mob control it was dearly earned by the surprising (and to Persia, embarrassing) Baha’i resilience. Under Quddus’s leadership the makeshift fort held out for seven months. Half of those original 18 “Letters of the Living” disciples would die in the engagement — the largest upheaval during those formative years.
At last, having finally been reduced to near-starvation by the encirclement, the Baha’i defenders surrendered on the guarantee of safe passage — a guarantee that was immediately violated, with most of the former “garrison” massacred on the spot on May 10.
Quddus was preserved for special treatment in Barfurush several days later: not judicial execution, but simply handing over to an angry rabble who tore him apart.
The Bab, already imprisoned pending the passion he would suffer the following year, was said to be so devastated at learning of Quddus’s fate that he could scarcely write any longer: “the deep grief which he felt had stilled the voice of revelation and silenced His pen. How deeply He mourned His loss! What cries of anguish He must have uttered as the tale of the siege, the untold sufferings, the shameless betrayal, and the wholesale massacre of the companions of Shaykh Tabarsi reached His ears and was unfolded before His eyes!” (Source)
