The time was the hour before sunset, on the 22nd day of May, 1844. The participants were the Bab, a twenty-five year old siyyid, of pure and holy lineage, and the young Mulla Husayn, the first to believe in Him. Their meeting immediately before that interview seemed to be purely fortuitous. The interview itself was protracted till the hour of dawn. The Host remained closeted alone with His guest, nor was the sleeping city remotely aware of the import of the conversation they held with each other. No record has passed to posterity of that unique night save the fragmentary but highly illuminating account that fell from the lips of Mulla Husayn.
"I sat spellbound by His utterance, oblivious of time and of those who awaited me," he himself has testified, after describing the nature of the questions he had put to his Host and the conclusive replies he had received from Him, replies which had established beyond the shadow of a doubt the validity of His claim to be the promised Qá'im. "Suddenly the call of the Mu'adhdhin, summoning the faithful to their morning prayer, awakened me from the state of ecstasy into which I seemed to have fallen. All the delights, all the ineffable glories, which the Almighty has recounted in His Book as the priceless possessions of the people of Paradise -- these I seemed to be experiencing that night. Methinks I was in a place of which it could be truly said: 'Therein no toil shall reach us, and therein no weariness shall touch us;' 'no vain discourse shall they hear therein, nor any falsehood, but only the cry, "Peace! Peace!"'; 'their cry therein shall be, "Glory to Thee, O God!" and their salutation therein, "Peace!", and the close of their cry, "Praise be to God, Lord of all creatures!"' Sleep had departed from me that night. I was enthralled by the music of that voice which rose and fell as He chanted; now swelling forth as He revealed verses of the Qayyúmu'l-Asmá', again acquiring ethereal, subtle harmonies as He uttered the prayers He was revealing. At the end of each invocation, He would repeat this verse: 'Far from the glory of thy Lord, the All-Glorious, be that which His creatures affirm of Him! And peace be upon His Messengers! And praise be to God, the Lord of all beings!'"
"This Revelation," Mulla Husayn has further testified, "so suddenly and impetuously thrust upon me, came as a thunderbolt which, for a time, seemed to have benumbed my faculties. I was blinded by its dazzling splendor and overwhelmed by its crushing force. Excitement, joy, awe, and wonder stirred the depths of my soul. Predominant among these emotions was a sense of gladness and strength which seemed to have transfigured me. How feeble and impotent, how dejected and timid, I had felt previously! Then I could neither write nor walk, so tremulous were my hands and feet. Now, however, the knowledge of His Revelation had galvanized my being. I felt possessed of such courage and power that were the world, all its peoples and its potentates, to rise against me, I would, alone and undaunted, withstand their onslaught. The universe seemed but a handful of dust in my grasp. I seemed to be the voice of Gabriel personified, calling unto all mankind: 'Awake, for, lo! the morning Light has broken. Arise, for His Cause is made manifest. The portal of His grace is open wide; enter therein, O peoples of the world! For He Who is your promised One is come!'"
