It was still early in the afternoon when the Báb requested Ḥájí Mírzá Siyyid `Alí to bring His pen-case and some paper. He then started to reveal His commentary on the Súrih of Kaw[_th_]ar. How am I to describe this scene of inexpressible majesty? Verses streamed from His pen with a rapidity that was truly astounding. The incredible swiftness of His writing, the soft and gentle murmur of His voice, and the stupendous force of His style, amazed and bewildered me. He continued in this manner until the approach of sunset. He did not pause until the entire commentary of the Súrih was completed. He then laid down His pen and asked for tea. Soon after, He began to read it aloud in my presence. My heart leaped madly as I heard Him pour out, in accents of unutterable sweetness, those treasures enshrined in that sublime commentary. I was so entranced by its beauty that three times over I was on the verge of fainting. He sought to revive my failing strength with a few drops of rose-water which He caused to be sprinkled on my face. This restored my vigour and enabled me to follow His reading to the end.[7] [Footnote CD: Qur'án, cviii. Kaw[_th_]ar is said to be a river in Paradise.] The Báb's conquest of Siyyid Yaḥyá was total.

Siyyid Yaḥyá has stated: We verified all the traditions in the text and found them to be entirely accurate. Such was the state of certitude to which I had attained that if all the powers of the earth were to be leagued against me they would be powerless to shake my confidence in the greatness of His Cause.[8] Siyyid Yaḥyá had stayed away for such a long time from the Governor's residence that Ḥusayn [_Kh_]án's suspicions were aroused. To his impatient queries, Siyyid Yaḥyá replied: No one but God, who alone can change the hearts of men, is able to captivate the heart of Siyyid Yaḥyá. Whoso can ensnare his heart is of God, and His word unquestionably the voice of Truth.[9] Ḥusayn [_Kh_]án was nonplussed and, for the moment, could only hold his peace; but he wrote bitterly to Muḥammad [_Sh_]áh to denounce Siyyid Yaḥyá. Nabíl-i-A`ẓam states that Muḥammad [_Sh_]áh reprimanded his Governor, replying:
