One night, after supper, the Imám-Jum’ih, whose curiosity had been excited by the extraordinary traits of character which his youthful Guest had revealed, ventured to request Him to reveal a commentary on the Súrih of Va’l-‘Asr. His request was readily granted. Calling for pen and paper, the Báb, with astonishing rapidity and without the least premeditation, began to reveal, in the presence of His host, a most illuminating interpretation of the aforementioned Súrih. It was nearing midnight when the Báb found Himself engaged in the exposition of the manifold implications involved in the first letter of that Súrih. That letter, the letter ‘váv’ upon which Shaykh Ahmad-i-Ahsá’í had already laid such emphasis in his writings, symbolised for the Báb the advent of a new cycle of Divine Revelation, and has since been alluded to by Bahá’u’lláh in the “Kitab-i-Aqdas” in such passages as “the mastery of the Great Reversal” and “the Sign of the Sovereign.” The Báb soon after began to chant, in the presence of His host and his companions, the homily with which He had prefaced His commentary on the Súrih. Those words of power confounded His hearers with wonder. They seemed as if bewitched by the magic of His voice. Instinctively they started to their feet and, together with the Imám-Jum’ih, reverently kissed the hem of His garment. Mullá Muḥammad-Taqíy-i-Haratí, an eminent mujtahid, broke out into a sudden expression of exultation and praise. “Peerless and unique,” he exclaimed, “as are the words which have streamed from this pen, to be able to reveal, within so short a time and in so legible a writing, so great a number of verses as to equal a fourth, nay a third, of the Qur’án, is in itself an achievement such as no mortal, without the intervention of God, could hope to perform. Neither the cleaving of the moon nor the quickening of the pebbles of the sea can compare with so mighty an act.”
