Nabil explains that according to Baha’u’llah’s brother, Áqáy-i-Kalím, sometime during this homecoming period a Bábí by the name of Mullá Shaykh 'Alí of Turshíz, entitled 'Azím, a veteran of the Faith, approached Baha’u’llah to enlist His support and gain His advice for a plan to assassinate the young Sháh and his new Prime Minister who were deemed to be the source of the continuing persecutions. Supported by his group of Bábí conspirators, 'Azím also aspired to be the successor of the Báb. They also thought that the Sháh's death might be a propitious time for the advancement of the Bábí Cause. Baha’u’llah, however, condemned 'Azím’s designs and advised him in most emphatic terms to abandon the plan he had conceived, and disassociated himself entirely from the intended rash act, warning him that fresh disasters of unprecedented magnitude would thus be precipitated. But 'Azím and his Bábí conspirators chose to disregard Baha’u’llah’s warnings. They continued their secret meeting in various homes, including that of Haji Sulayman Khan, another veteran of the Faith, the same brave and devoted man who had, at the behest of Baha'u'llah, gone to Tabriz to recover the remains of the martyred Báb and bring them to Tihran. Amongst those Bábis attached to 'Azím were three young men, a confectioner, an engraver of Qum, and a third person who apparently had suffered much at the hands of the adversaries of his Faith. In the eyes of these youths, the young Shah was the source of all the calamities that had befallen them, and so they plotted to assassinate him. It is not known how many were involved in this criminal folly, but 'Azím certainly was.
