Eventually Siyyid Káẓim travelled north to be in his company, and together they went to Kirmánsháh, as the Prince-Governor had been urgently begging his father to let Shaykh Aḥmad visit him. They stayed in Kirmánsháh as long as the Governor lived. After his premature death, they departed for Karbilá, where Shaykh Aḥmad, his zeal unabated and his powers untouched by advancing years, preached and taught. He was in his early eighties when he took the road to Mecca and Medina. From that journey he did not return and lies buried in the famed cemetery of Baqi`, in the vicinity of the Tomb of the Prophet Muḥammad.

Shaykh Aḥmad's constant theme was the near advent of the Deliverer of the Latter Days, promised to the world of Islám, the Qá'im of the House of Muḥammad or the Mihdí (Mahdí).[1] In the course of his last pilgrimage to the holy cities of Arabia, he told a merchant from Iṣfahán[C] who was with him: 'You will attain the presence of the Báb; salute Him on my behalf.'[2] Shaykh Aḥmad did not believe in physical resurrection nor in the physical ascent (Mi`ráj)[D] of the Prophet Muḥammad to heaven on the night that the Angel Gabriel took Him to view the celestial world. Mi`ráj was an experience of the spirit, Shaykh Aḥmad maintained. Moreover he asserted that the signs and portents of the coming of the Qá'im, given by the Prophet and the Imáms, were allegorical. These and similar doctrines were anathema to the orthodox, but while Shaykh Aḥmad lived, royal patronage muted their hostile criticism.

Siyyid Káẓim (1793-1843), who, in accordance with the will of Shaykh Aḥmad, succeeded him in guiding his disciples, was the son of Siyyid Qásim of Rasht, a town in northern Írán close to the Caspian Sea. He came from a family of well-known merchants and was no more than thirty-three years old when he occupied the seat of authority. The orthodox divines now began their vitriolic assaults in earnest until, at last, Siyyid Káẓim felt that he needed solid support in Írán from the ranks of the orthodox. For that purpose he chose one of his ablest disciples, Mullá Ḥusayn, a native of the small town of Bushrúyih in Khurásán, to go to Iṣfahán and secure the aid of Ḥájí Siyyid Muḥammad-Báqir-i-Rashtí, a noted divine whose influence was felt far and wide. Mullá Ḥusayn succeeded brilliantly in accomplishing the mission entrusted to him, obtained the support of that famous man in writing, and then proceeded to Mashhad to acquire a similar pledge from yet another powerful divine.

In the meantime not only did Siyyid Káẓim suffer from the intrigues and onslaughts of his adversaries headed by Siyyid Ibráhím-i-Qazvíní, but the whole of Karbilá was thrown into turmoil. These disorders were of long standing and gradually the authority of the Ottoman government had ceased to exist. Within the town there were several factions at odds with one another, but all determined to resist the re-establishment of Ottoman power. Two successive Válís (governor-generals) of `Iráq tried to force the people of Karbilá to submission, but failed conspicuously. However, in the closing months of the year 1842, Najíb Páshá, a man resolute and even obstinate, came to occupy the post of Válí. Affairs in Karbilá had gradually gone from bad to worse. Lawlessness had increased and mob rule prevailed. Najíb Páshá's first thought was to resolve this problem which had baffled his predecessors. He tried to negotiate a settlement, but neither he nor the rebels of Karbilá could really trust one another. Najíb Páshá moved near-by to Musayyib and sent Sar`askar (Colonel) Sa`du'lláh Páshá with a small force to reduce the town. Negotiations proceeded apace. Emissaries came and went. Persian princes, who lived in Karbilá, took part in the negotiations, but nothing was achieved.

During those fatal weeks, at the end of the year 1842 and the beginning of 1843, Siyyid Káẓim, who was greatly respected both for his wisdom and humanity,[E] took a leading role, urging all parties to act with moderation and in a spirit of conciliation. Twice, in company with a small delegation, he visited the camps of Najíb Páshá and Sa`du'lláh Páshá outside Karbilá. Lieutenant-Colonel Farrant, the British Special Commissioner, reported his efforts to Constantinople:
claimed the throne of Írán. He showed great benevolence
towards the divines of Karbilá and Najaf, sent them money and stood up for them. However, he was unsuccessful and betook himself to Karbilá. There he fell on hard times and suffered poverty. He expected the divines to come to his help and applied to them, one by one. But none heeded him. One night he and his family had to go to bed hungry. At midnight he heard a knock on his door. When he opened it he found someone, who had pulled his `abá over his head so as to hide his face. This man put a purse with money in it into his hands and went away.

'Time passed. Indigence and want recurred. Again the same person, head covered with `abá, came at midnight, handed a sum of money and went away without a word. To the repeated question "who are you?" he gave no answer. Then, that man came a third time with a purse containing money. This time `Alí-Sháh followed him and saw him enter the house of Ḥájí Siyyid Káẓim and shut the door. `Alí-Sháh related this event in many gatherings. He used to say: "O people! I am not a Shaykhí, but this deed is the work of righteousness. None but a man of truth would act in this way."'[3]

The Chief Priest Hajee Seid Kausem did all in his power to prevent hostilities, he preached against their proceedings, he was abused and threatened, they would not listen to him—this I have heard from many people at Kerbella—at this time all were unanimous in defending the place

... to the very last he entreated them to listen to the Pacha but without avail, he shewed great courage on the occasion, as he had all the chief Geramees[F] and Mollahs against him.[4]

Unhappily, his counsel was ignored by both rebels and Turks. In January 1843, after a siege of twenty-four days, the holy city was taken by assault, causing great suffering to the innocent inhabitants. The files of the Public Record Office in London contain several documents that throw light on this episode, as well as on the central part played by Siyyid Káẓim. (See [Appendix I].)

During the siege Ḥájí Siyyid Káẓim had spent himself in an effort to forestall violence and protect all parties to the conflict. Although only fifty years of age, he became aware that his life was nearing its close. He was warned of this, we are told, by the dream of an Arab shepherd who recounted it to him. When his disciples expressed their distress, Siyyid Káẓim replied:

Is not your love for me for the sake of that true One whose advent we all await? Would you not wish me to die, that the promised One may be revealed?[5]
