However, it was Yahya’s subsequent attempt on Bahá’u’lláh’s life that brought about "an unprecedented commotion in the community". It involved Ustad Muhammad-‘Aliy-i-Salmani, a traditional barber who served as Bahá’u’lláh’s bath attendant. Salmani reported that Yahya suddenly began to show kindness to him, then one day insinuated it would be "a great service" to their religion if he assassinated Bahá’u’lláh while attending to him in the bath. Salmani was so outraged he said his immediate thought was to kill Yahya—he hesitated only because he knew doing that would displease Bahá’u’lláh. Agitated, he informed Bahá’u’lláh’s faithful brother Mirza Musa of the incident, who advised him to ignore it, saying Yahya had thought of this for years. Still upset, Salmani told ‘Abdu’l-Bahá, Bahá’u’lláh’s eldest son, about the matter, who told him not to speak of it to others. Salmani finally informed Bahá’u’lláh, who likewise said he should not mention it to anyone. Until this incident, because Yahya was a half-brother whom Bahá’u’lláh always treated with kindness and care, most in the Bábí community also showed Yahya respect, even if they did not accept his claims to a special religious status. However, when Salmani was unable to keep silent and openly related to others what Yahya had asked of him, Yahya’s actions and intentions—so contrary to the Báb’s teachings—incited great turmoil amidst the Bábís. Having given his younger sibling ample guidance and opportunities to live as a Bábí should, and having repeatedly forgiven him for things he had done in the past, Bahá’u’lláh decided the time had come to formally declare to Mirza Yahya that he was God’s latest manifestation, the Promised One of the Báb, "Him whom God shall make manifest"—because doing so would require him to obey Bahá’u’lláh if Yahya were to remain faithful to the Báb. Bahá’u’lláh made that declaration to Yahya in early March 1866 through a tablet penned in Bahá’u’lláh’s own handwriting, and read aloud to Yahya by Bahá’u’lláh’s amanuensis. Besides unequivocally proclaiming his spiritual station, Bahá’u’lláh called upon Yahya "to recognize and support him as the Báb had explicitly instructed him to do." Mirza Yahya’s response was to counter that he, not Bahá’u’lláh, was the promised manifestation mentioned by the Báb. This step by Yahya promptly resulted in almost all Bábís in Adrianople, who were already devoted to Bahá’u’lláh, deciding to have nothing further to do with Yahya or his few supporters.
