Siyyid Yahyá met the Báb at the home of Hájí Mírzá Siyyid ‘Alí, and exercised in his attitude towards Him the courtesy which Azím had counselled him to observe. For about two hours he directed the attention of the Báb to the most abstruse and bewildering themes in the metaphysical teachings of Islám, to the obscurest passages of the Qur’án, and to the mysterious traditions and prophecies of the imáms of the Faith. The Báb at first listened to his learned references to the law and prophecies of Islám, noted all his questions, and began to give to each a brief but persuasive reply. The conciseness and lucidity of His answers excited the wonder and admiration of Siyyid Yahyá. He was overpowered by a sense of humiliation at his own presumptuousness and pride. His sense of superiority completely vanished. As he arose to depart, he addressed the Báb in these words: “Please God, I shall, in the course of my next audience with You, submit the rest of my questions and with them shall conclude my enquiry.” As soon as he retired, he joined Azím, to whom he related the account of his interview. “I have in His presence,” he told him, “expatiated unduly upon my own learning. He was able in a few words to answer my questions and to resolve my perplexities. I felt so abased before Him that I hurriedly begged leave to retire.” Azím reminded him of his counsel, and begged him not to forget this time the advice he had given him.
