“O Muḥammad!”, are some of the words He uttered on that memorable occasion, as testified by Himself in a Tablet, “He Who is the Spirit hath, verily, issued from His habitation, and with Him have come forth the souls of God’s chosen ones and the realities of His Messengers. Behold, then, the dwellers of the realms on high above Mine head, and all the testimonies of the Prophets in My grasp. Say: Were all the divines, all the wise men, all the kings and rulers on earth to gather together, I, in very truth, would confront them, and would proclaim the verses of God, the Sovereign, the Almighty, the All-Wise. I am He Who feareth no one, though all who are in heaven and all who are on earth rise up against me.... This is Mine hand which God hath turned white for all the worlds to behold. This is My staff; were We to cast it down, it would, of a truth, swallow up all created things.” Mír Muḥammad, who had been sent ahead to announce Bahá’u’lláh’s arrival, soon returned, and informed Him that he who had challenged His authority wished, owing to unforeseen circumstances, to postpone for a day or two the interview. Upon His return to His house Bahá’u’lláh revealed a Tablet, wherein He recounted what had happened, fixed the time for the postponed interview, sealed the Tablet with His seal, entrusted it to Nabíl, and instructed him to deliver it to one of the new believers, Mullá Muḥammad-i-Tabrízí, for the information of Siyyid Muḥammad, who was in the habit of frequenting that believer’s shop. It was arranged to demand from Siyyid Muḥammad, ere the delivery of that Tablet, a sealed note pledging Mírzá Yaḥyá, in the event of failing to appear at the trysting-place, to affirm in writing that his claims were false. Siyyid Muḥammad promised that he would produce the next day the document required, and though Nabíl, for three successive days, waited in that shop for the reply, neither did the Siyyid appear, nor was such a note sent by him. That undelivered Tablet, Nabíl, recording twenty-three years later this historic episode in his chronicle, affirms was still in his possession, “as fresh as the day on which the Most Great Branch had penned it, and the seal of the Ancient Beauty had sealed and adorned it,” a tangible and irrefutable testimony to Bahá’u’lláh’s established ascendancy over a routed opponent.
