All the arrogance of the warden left him. He was totally conquered. He became humble. The first words that he uttered were:

A poor man, a shaykh, is yearning to attain Your presence. He lives in a masjid [mosque] outside the gate of Máh-Kú. I pray You that I myself be allowed to bring him to this place that he may meet You. By this act I hope that my evil deeds may be forgiven, that I may be enabled to wash away the stains of my cruel behaviour toward Your friends.[8]

He went away and returned with Shaykh Ḥasan-i-Zunúzí.

`Alí Khán's change of heart and attitude radically altered the situation. The prison gates no longer barred the Báb from His followers. Bábís came from everywhere to attain the presence of their Lord, among them Mullá Ḥusayn, the Bábu'l-Báb. The Báb received him at the gate of the castle and celebrated the Feast of Naw-Rúz with him. Ere his departure, the Báb directed him to visit Tabríz and other towns of the province of Ádharbáyján, and then proceed to Zanján, Qazvín, Ṭihrán, and finally to the province of Mázindarán.

`Alí Khán's devotion to the person of the Báb increased day by day. He did everything possible to mitigate the rigours of prison life. Every Friday he came up the mountain to offer his homage. Ḥájí Mírzá Áqásí was alarmed by the news reaching him from Máh-Kú, and so was the Russian Minister in Ṭihrán, Prince Dimitri Ivanovich Dolgorukov. In dispatches to Count Nesselrode, the Minister of Foreign Affairs, dated February 4th and December 24th 1848, he mentions that, in the previous year, the Báb had been removed from the vicinity of the Russian border by his demand.[9] This assertion is borne out by a letter of Mullá Aḥmad-i-Ibdál, one of the Letters of the Living, written when he was in Káẓimayn, close to Baghdád. It is not clear to whom the letter is addressed, most probably to one of the uncles of the Báb.[10] Mullá Aḥmad writes:

These days, God willing, I intend to go and attain the presence of my Lord.... These days pilgrims arrived here from Urúmíyyih. I sought the news of my Lord from them. They said that He was in a district of Urúmíyyih, called Chihrúm [Chihríq?]. The Governor of Urúmíyyih wished, at first, to keep Him in the town itself, but the clerics had taken fright lest disturbances might arise, and had refused their consent; curses of God rest upon them. It is said that the Governor is acting with kindness, and from the towns of Adharbáyján people come in large groups, attain His presence and return believers. According to what has been related there is a tremendous upsurge, that is to say, many, many people have become devoted to Him.... And as to the reason for the departure of Dhikr, on Him be peace from Máh-Kú, it is this, that the Russian Envoy had heard that He was in Máh-Kú, and, being afraid of disturbance, told the Vizier, Ḥájí Mírzá Áqásí: 'Send the Dhikr, on whom be peace, to some other area of your realms, because Máh-Kú is on the frontier and close to our territory, and we are afraid of disturbances; a few years ago, a certain Mullá Ṣádiq claimed to be the deputy [of the Imám] and within a month gathered 30,000 followers round him.' Russians had witnessed that and had taken fright.

`Abdu'l-Bahá states that the Báb's incarceration in the castle of Máh-Kú lasted nine months. According to Nabíl-i-A`ẓam, on the twentieth day after Naw-Rúz (April 9th 1848), He left that mountain fastness on the Russian and Turkish frontiers.[11]

At Máh-Kú the Báb revealed the Dalá'il-i-Sab`ih (The Seven Proofs) and began the composition of the Persian Bayán[DF] (Exposition or Utterance). Nabíl-i-A`ẓam writes:

I have heard Shaykh Ḥasan-i-Zunúzí bear witness to the following: 'The voice of the Báb, as He dictated the teachings and principles of His Faith, could be clearly heard by those who were dwelling at the foot of the mountain. The melody of His chanting, the rhythmic flow of the verses which streamed from His lips caught our ears and penetrated into our very souls. Mountain and valley re-echoed the majesty of His voice. Our hearts vibrated in their depths to the appeal of His utterance.'[12]
