Refusing to comply with the wishes of the royal envoys, the Russian Minister requested Bahá’u’lláh to proceed to the home of the Grand Vizir [Mírzá Áqá Khán], to whom he formally communicated his wish that the safety of the Trust the Russian government was delivering into his keeping should be insured. This purpose, however, was not achieved because of the Grand Vizir’s apprehension that he might forfeit his position if he extended to the Accused the protection demanded for Him.

The news of the arrival of Bahá’u’lláh greatly surprised the officers of the imperial army. Násiri’d-Dín Sháh himself was amazed at the bold and unexpected step which a man who was accused of being the chief instigator of the attempt upon his life had taken. He immediately sent one of his trusted officers to the [Russian] legation, demanding that the Accused be delivered into his hands.
