This inevitably brought them into conflict with the new hard-line Shiism of some of the ulema, who drove Mulla Sadra out of Isfahan. For ten years he was forced to live in a small village near Qum. During this period of solitude, he realized that despite his devotion to mystical philosophy, his approach to religion had still been too cerebral. The study of jurisprudence (fiqh) or extrinsic theology could only give us information about religion; it could not yield the illumination and personal transformation that is the ultimate goal of the religious quest. It was only when he began seriously to practice the mystical techniques of concentration and descended deeply into the alam al-mithal within himself that his heart “caught fire” and “the light of the divine world shone forth upon me … and I was able to unravel mysteries that I had not previously understood,” he explained later in his great work al-Asfar al-Arbaah49 (The Four Journeys of the Soul).
Sadra’s mystical experiences convinced him that human beings could achieve perfection in this world. But, true to the conservative ethos, the perfection that he envisaged was not an evolution to a new and higher state, but a return to the original pure vision of Abraham and the other prophets. It was also a return to God, the Source of all existence. But this did not mean that the mystic abjured the world. In The Four Journeys of the Soul, he described the mystical journey of a charismatic political leader. First, he must journey from man to God. Next he travels in the divine sphere, contemplating each of God’s attributes until he arrives at an intuitive sense of their indissoluble unity. Gazing thus on the face of God, he is transformed and has a new perception of what monotheism really means and an insight that is not unlike that enjoyed by the Imams. In his third journey, the leader travels back to humankind, and finds that he now sees the world quite differently. His fourth and final quest is to preach God’s word in the world and to find new ways to institute the divine law and reorder society in conformity with God’s will.50 It was a vision that linked the perfection of society to a simultaneous spiritual development. The establishment of justice and equity here below could not be achieved without a mystical and religious underpinning. Mulla Sadra’s vision fused politics and spirituality, which had become separate in Twelver Shiism, seeing the rational effort that was essential for the transformation of society in the mundane world as inseparable from the mythical and mystical context that gave it meaning. Mulla Sadra had thus proposed a new model of Shii leadership, which would have a profound impact upon Iranian politics in our own day.
The mystical political leader of Mulla Sadra’s vision would have divine insight, but that did not mean that he could impose his own opinions and religious practice on others by force. If he did that, in Sadra’s view, he denied the essence of religious truth. Sadra was vehemently opposed to the growing power of the ulema, and was especially disturbed by a wholly new idea that was gaining ground in Iran during the seventeenth century. Some ulema now believed that most Muslims were incapable of interpreting the fundamentals (usul) of the faith for themselves; because the ulema were the only official spokesmen of the Hidden Imam, ordinary folk must, therefore, select a mujtahid who had been deemed capable of exercising ijtihad (“independent reasoning”) and model their behavior on his legal rulings. Sadra was appalled by these claims of the Usulis, as the proponents of this view were called.51 In his view, any religion that was based on such servile imitation (taqlid) was inherently “polluted.”52 All Shiis were quite capable of understanding the traditions (akhbar) of the Prophets and the Imams, and could work out solutions for themselves, based on reason and the spiritual insights they derived from prayer and ritual.
As the seventeenth century progressed, conflict between the Usulis and their opponents became more heated. Safavid power was beginning to decline, and society starting to fragment. People looked to the ulema as the only authorities capable of restoring order, but they differed among themselves about the nature of their authority. At this stage, most Iranians opposed the Usulis and followed the so-called Akhbaris, who relied on past tradition. The Akhbaris condemned the use of ijtihad and promoted a narrowly literal interpretation of the Koran and the Sunnah. They insisted that all legal decisions must be based on explicit statements of the Koran, the Prophet, or the Imams. If cases arose where there were no inspired rulings, the Muslim jurist must not depend upon his own judgment but should refer the matter to the secular courts.53 The Usulis wanted a more flexible approach. Jurists could use their own reasoning powers to reach valid decisions, based on legal principles hallowed by Islamic tradition. They thought that the Akhbaris would get so enmeshed in the past that Islamic jurisprudence would be unable to meet new challenges. In the absence of the Hidden Imam, they argued, no jurist could have the last word and no precedent could be binding. Indeed, they went so far as to say that the faithful should always follow the rulings of a living mujtahid rather than a revered authority of the past. Both sides were trying to remain true to the conservative spirit at a time of social and political instability, and both were principally concerned with the divine law. Neither the Usulis nor the Akhbaris insisted on intellectual conformity; it was only in matters of behavior or religious practice that the faithful must submit to either a literal reading of scripture or the rulings of a mujtahid. Nevertheless, both sides had lost something. The Akhbaris had confused the primordial divine imperative symbolized by the law with the historical traditions of the past; they had become literalists, and were essentially out of touch with the symbolic religion of the old Shiah. In their vision, the faith had become a series of explicit directives. The Usulis had more confidence in human reason, which was still anchored in the mythos of their religion. But in demanding that the faithful conform to their judgment, they had lost Mulla Sadra’s belief in the sacred freedom of the individual.
By the end of the seventeenth century, it had become crucial to establish a legal authority that could compensate for the weakness of the state. Trade had declined, bringing economic insecurity, and the incompetence of the later shahs made their state vulnerable. When Afghan tribes attacked Isfahan in 1722, the city surrendered ignominiously. Iran entered a period of chaos, and, for a time, it seemed that it might even cease to exist as a separate entity. The Russians invaded from the north, the Ottomans from the west, and the Afghans consolidated their position in the south and east. Tahmasp II, the third son of Sultan-Husain Shah, however, had survived the siege of Isfahan, and, with the help of Nadir Khan, a chieftain of the Iranian Afshar tribe, he succeeded in driving out the invaders. In 1736, Nadir Khan dispensed with Tahmasp Shah and had himself acclaimed as monarch. He ruled the country brutally but effectively until he was assassinated in 1748. A dark anarchic interregnum then ensued, until Aqa Muhammad Khan of the Turcoman Qajar tribe seized control and managed to consolidate his rule in 1794.54 This new Qajar dynasty would remain in power until the early twentieth century.
During these grim years, there were two important religious developments. Nadir Khan had tried unsuccessfully to reestablish the Sunnah in Iran; as a result, the leading ulema left Isfahan and took refuge in the holy shrine cities of Najaf and Kerbala in the Ottoman region of Iraq. At first this seemed a setback, but in the long term it proved a gain for the ulema. In Kerbala and Najaf, they achieved still greater autonomy. They were out of the shahs’ reach politically, and financially independent, and gradually they became an alternative establishment, superbly placed to challenge the court.55 The second major change of the period was the victory of the Usulis, achieved by the somewhat violent methods of the eminent scholar Vahid Bihbehani (1705–92), who defined the role of ijtihad with great clarity,
