“at this critical juncture” Bahá’u’lláh “was moved to disclose [to Mírzá Áqá Ján] …a glimpse of the as yet unrevealed glory of His station”

To Mírzá Áqá Ján, “the first to believe” in Him, designated later as Khádimu’lláh (Servant of God)—a Bábí youth, aflame with devotion, who, under the influence of a dream he had of the Báb, and as a result of the perusal of certain writings of Bahá’u’lláh, had precipitately forsaken his home in Káshán and traveled to ‘Iráq, in the hope of attaining His presence, and who from then on served Him assiduously for a period of forty years in his triple function of amanuensis, companion and attendant—to him Bahá’u’lláh, more than to any one else, was moved to disclose, at this critical juncture, a glimpse of the as yet unrevealed glory of His station.

This same Mírzá Áqá Ján, recounting to Nabíl his experiences, on that first and never to be forgotten night spent in Karbilá, in the presence of his newly-found Beloved, Who was then a guest of Hájí Mírzá Hasan-i-Hakím-Báshí, had given the following testimony:

“As it was summer-time Bahá’u’lláh was in the habit of passing His evenings and of sleeping on the roof of the House.… That night, when He had gone to sleep, I, according to His directions, lay down for a brief rest, at a distance of a few feet from Him. No sooner had I risen, and … started to offer my prayers, in a corner of the roof which adjoined a wall, than I beheld His blessed Person rise and walk towards me. When He reached me He said: ‘You, too, are awake.’ Whereupon He began to chant and pace back and forth. How shall I ever describe that voice and the verses it intoned, and His gait, as He strode before me! Methinks, with every step He took and every word He uttered thousands of oceans of light surged before my face, and thousands of worlds of incomparable splendor were unveiled to my eyes, and thousands of suns blazed their light upon me! In the moonlight that streamed upon Him, He thus continued to walk and to chant. Every time He approached me He would pause, and, in a tone so wondrous that no tongue can describe it, would say: ‘Hear Me, My son. By God, the True One! This Cause will assuredly be made manifest. Heed thou not the idle talk of the people of the Bayán, who pervert the meaning of every word.’ In this manner He continued to walk and chant, and to address me these words until the first streaks of dawn appeared.… Afterwards I removed His bedding to His room, and, having prepared His tea for Him, was dismissed from His presence.”

“words of warning, of counsel and of assurance” from Bahá’u’lláh “at a time when the shadows were beginning to deepen around Him”

Little wonder that from the pen of Bahá’u’lláh, Who was as yet unable to divulge the Secret that stirred within His bosom, these words of warning, of counsel and of assurance should, at a time when the shadows were beginning to deepen around Him, have proceeded:

“The days of tests are now come. Oceans of dissension and tribulation are surging, and the Banners of Doubt are, in every nook and corner, occupied in stirring up mischief and in leading men to perdition.… Suffer not the voice of some of the soldiers of negation to cast doubt into your midst, neither allow yourselves to become heedless of Him Who is the Truth, inasmuch as in every Dispensation such contentions have been raised. God, however, will establish His Faith, and manifest His light albeit the stirrers of sedition abhor it.… Watch ye every day for the Cause of God.… All are held captive in His grasp. No place is there for any one to flee to. Think not the Cause of God to be a thing lightly taken, in which any one can gratify his whims. In various quarters a number of souls have, at the present time, advanced this same claim. The time is approaching when … every one of them will have perished and been lost, nay will have come to naught and become a thing unremembered, even as the dust itself.” 

- Shoghi Effendi (‘God Passes By)

Mirzá Yahyá had “established himself… in a dilapidated quarter of the city” of Baghdád, and Siyyid Muhammad-i-Isfaháni “settled in Karbilá” and together they were “kindling dissensions and in deranging the life of the exiles and of the community that had gathered about them”

The former [Mirzá Yahyá] had, after the execution of the Báb, sustained such a violent shock that his faith almost forsook him. Wandering for a time, in the guise of a dervish, in the mountains of Mázindarán, he, by his behavior, had so severely tested the loyalty of his fellow-believers in Núr, most of whom had been converted through the indefatigable zeal of Bahá’u’lláh, that they too wavered in their convictions, some of them going so far as to throw in their lot with the enemy. He subsequently proceeded to Rasht, and remained concealed in the province of Gílán until his departure for Kirmánsháh, where in order the better to screen himself he entered the service of a certain ‘Abdu’lláh-i-Qazvíní, a maker of shrouds, and became a vendor of his goods. He was still there when Bahá’u’lláh passed through that city on His way to Baghdád, and expressing a desire to live in close proximity to Bahá’u’lláh but in a house by himself where he could ply some trade incognito, he succeeded in obtaining from Him a sum of money with which he purchased several bales of cotton and then proceeded, in the garb of an Arab, by way of Mandalíj to Baghdád. He established himself there in the street of the Charcoal Dealers, situated in a dilapidated quarter of the city, and placing a turban upon his head, and assuming the name of Ḥájí ‘Alíy-i-Lás-Furúsh, embarked on his newly-chosen occupation. Siyyid Muhammad had meanwhile settled in Karbilá, and was busily engaged, with Mírzá Yaḥyá as his lever, in kindling dissensions and in deranging the life of the exiles and of the community that had gathered about them.
