The details of Husayn's actual death are fairly gruesome.
It was in this sense, and not, as has been often asserted, in the sense of " Gate of God " or " Gate of Religion," that the title Bab was understood and assumed by Mirz&`Ali Muhammad; but,though still generally thus styled by non-Babis, he soon assumed the higher title of .Nugta (" Point "), and the title Bab, thus left vacant, was conferred on his ardent disciple, Mull& Husayn of Bushrawayh.
Of these risings the first (December 1848-July 1849) took place in Mazandaran, at the ruined shrine of Shaykh Tabarsi, near Barfurush, where the Babis, led by Mulla Muhammad `Ali of Barfurush and Mulla Husayn of Bushrawayh (" the first who believed "), defied the shah's troops for seven months before they were finally subdued and put to death.
He lived, however, in great seclusion, leaving the direction of affairs almost entirely in the hands of his elder halfbrother (born 12th November 1817), Mirth Husayn `Ali, entitled Baha' u'llah (" the Splendour of God "), who thus gradually became the most conspicuous and most influential member of the sect, though in the Igan, one of the most important polemical works of the Babis, composed in 1858-1859, he still implicitly recognized the supremacy of Subh-i-Ezel.
