Abu Abdullah Muhammad, surnamed ash-Shakir was born in 122/740 in Medina. He passed his early life with his grandfather for 24 years and 10 years with his family in Medina. He however kept himself silent (samit) so long as he lived in Medina. He most probably left Medina soon after the death of his grandfather in 148/765.
The Abbasid caliph Mansur also died in 158/775 and was succeeded by his son Mahdi, who according to Ignaz Goldziher in 'Muslim Studies'(London, 1971, 2nd vol., p. 106), 'was listed by Ibn Adi as an inventor of hadiths.' He also died in 169/785 after ruling for 22 years, and was succeeded by his son, Hadi. He died in 170/786, and then his brother, Harun ar-Rashid became the next ruler till 193/809. He was also succeeded by his son, Amin.
The inimical opposition of the Abbasids against the Ismaili Imams was vigorously in continual. Abul Faraj Ispahani writes in 'al-Aghani' (12th vol., p. 17) that, 'Harun al-Rashid demanded of his poets that they combine his own praise with refutation of the claims of Ali's descendants and with attacks against the latter.' Abul Faraja further writes that, 'Harun ar-Rashid permitted himself to be glorified with things by which the prophets were praised; he did not disapprove of it and did not refuse it.' (Ibid. 12th vol., p. 18)
The most earliest description of Muhammad bin Ismail is found from the work of Tabari (3rd vol., p. 2218), and in the Ismaili sources summed up in the 4th volume of 'Uyun'l-Akhbar' (comp. 842/1438). Accordingly, Muhammad bin Ismail resided in Medina from where he sent his dais not only to spread Ismailism, but to search for a land of refuge where he could live unscathed. When Harun ar-Rashid learnt news of it, he sent his officials to arrest and bring the Imam to his court. When the caliph's men came to the house to carry out the orders, Muhammad bin Ismail entered an underground passage he had constructed inside his house and remained concealed until they had left. When the search for him had abated, he started on his journey, leaving behind his two sons. His whereabouts had been kept a closely guarded secret only the few specially privileged being acquainted with it and even they being pledged to the strictest secrecy.
It has been heretofore discussed that Musa Kazim had been staged as an Imam by the Abbasids on the ground of the fabricated theory of change of nass. The Abbasids had instituted an intensive search for Ismail, because they were well aware that Musa Kazim was not the true successor, otherwise he would have been executed very soon. They however failed to trace out Ismail and his son Muhammad. On the other side, the Abbasids noticed its reverse effect in Medina, where Musa Kazim was being truly adhered as an Imam. In the time of Harun ar-Rashid, finally Musa Kazim was arrested, who died in prison in 183/799. He should have been arrested and executed in 148/765, had he been truly succeeded his father.
Cyril Glasse writes in 'The Concise Encyclopaedia of Islam' (London, 1989, p. 197) that, 'The followers of Ismail, whose conception of the Imam was more absolute than that of the other Shiites, maintained on the contrary that the next Imam should be Ismail's son.'
Admittedly, it is learnt that after leaving Medina, Muhammad bin Ismail made his way towards Iran and Syria accompanied by Maymun al- Qaddah. The bitterest of the Abbasids' enmity was daily growing in intensity. Apprehending lest the enemies should resort to some violent measures against him, Muhammad assumed the name of Maymun al-Qaddah to elude discovery. Thus, the name Maymun al-Qaddah came to be used by two characters at one time. It was also resolved, if the real identity of the Imam be traced, Maymun al-Qaddah was to come forward as Muhammad bin Ismail to sacrifice his own life in order to protect the line of Imamate from extinction.
Henceforward, Muhammad bin Ismail had also a sobriquet of Maymun al-Qaddah to conceal his identity. In fact, Maymun al-Qaddah had a son, named Abdullah (d. 260/874), while Muhammad bin Ismail had also a son at the same time, called Abdullah (d. 212/828), surnamed al-Wafi Ahmad. With the passage of time, Muhammad became known as Maymun al-Qaddah in the places he resided, while Maymun al-Qaddah was treated as Muhammad bin Ismail in the regions he propagated Ismailism. Abdullah, the son of Maymun al-Qaddah was consequently considered as the son of Muhammad bin Ismail in the regions where the Imam had assumed the title of al-Qaddah. It therefore gave rise to the contrivance of a story that Abdullah (al-Wafi Ahmad) was the son of Maymun al-Qaddah on one hand, and Abdullah (bin Maymun al-Qaddah) was the son of Muhammad bin Ismail on other. Later on, it became an instrument for the anti-Fatimid propagandists, notably Ibn Razzam to join the lineage of the Fatimid Imams with that of Abdullah bin Maymun al-Qaddah instead of Abdullah (al-Wafi Ahmad) bin Muhammad bin Ismail. This is known as Qaddahid theory and became a weapon of the later Abbasids to discredit the Fatimid origin in 401/1010.
In the face of these facts, the Ismaili Imams had assumed the titles of the dais in one or more time during the veiled period, which is also sounded expressly in the letter of the Fatimid Imam al-Muizz (341-365/953-975), written in 354/965, addressing to his dai in Sind, called Jaylam bin Shayban. This important letter is well preserved by Idris Imaduddin (d. 872/1468) in the 5th volume of 'Uyun'l-Akhbar'(comp. 842/1438). It reads:- '.... These people have arbitrarily limited (the period of Imamate) by (the death of) Muhammad bin Ismail; and when he died, they said about him all what was said by them. They (also) thought that he entrusted the Imamate to some one who was not his son. And that his successor (similarly) entrusted the Imamate (to his own) successors, whose number has (also) reached the number of seven. They thought that the first (of these pseudo-Imams) was Abdullah bin Maymun al-Qaddah. All this is preached in order to prove their theory that there was no Imam after him (i.e., Muhammad bin Ismail), and that those who succeeded him were ordinary people. Thus they have cut what God ordered to be continuing (the line of Imams), opposing the command of God, given in the Koran (47:27). '....and We have made a word to remain after him.' The cause of this requires explanation. When the preaching in favour of Muhammad bin Ismail has spread, the Abbasid usurpers tried to lay their hands upon him, i.e. the person whose rights were claimed. Therefore (he and other) Imams went into concealment. Their dais used to refer to them under allegorical names, in accordance with the principle of taqiya, alluding to what they possessed and what was appropriate to them. They used to say, for instance, that the Imam, the son of Muhammad bin Ismail was Abdullah. And this was true. And with regard to his being the son of Maymun al-Qaddah, it was true that he was the son of Maymunu'n naqibat, i.e. of the 'Divinely blessed with success in his affairs,' of al-Qaddah (the flint) 'striking the sparks of guidance', i.e. 'lighing the light of the Divine wisdom'. Similar allegorical expressions were applied also to other Imams after him, at their own orders and instructions given to their dais. When such allegorical expressions reached those who know nothing about their real implications, and only took them literally, as we mentioned above, they fell into an error, and made others err after them, straying from the straight path. But if they would only do what God has ordered them to do, rallying around the Imams, they surely would know those who were otherwise hidden from them. Just as you know them now. But the blind, who has no one to lead him, or a stick in his hand, falls into an abyss from which no one can save him. The self-conceited fall into sin and error. So beware of thinking that God ever abandons humanity to itself. No, He does not abandon them even for a moment, leaving them without an Imam from the descendants of the Prophet. And the Imams can come to their office only by the commandments relating to Imamate....'
In addition, Hatim bin Imran bin Zuhra (d. 498/1104) writes in his 'al-Usul wa'l-Ahkam' that, 'The dais used their own names as nick-names for the Imams in order to protect them from persecution; some people were misled by this to such a degree that they said that the Imam, descendant of Muhammad bin Ismail was Abdullah bin Maymun al-Qaddah.' According to Arif Tamir in 'al-Qaramita' (p. 87), 'When Muhammad bin Ismail fled from the east and established in Palmyra in Syria, the centers of his activities; he called himself Maymun al-Qaddah.' Syed Abid Ali Abid writes in 'Political Theory of the Shiites' (cf. 'A History of Muslim Philosophy', ed. by M.M. Sharif, Germany, 1963, 1st. vol., p. 740) that, 'As a matter of fact, as the latest research has established beyond any doubt, Maimun was the name adopted by Imam Muhammad when he went into concealment. In other words, during the period of concealment those who were in his confidence knew Imam Muhammad to be a Maimun.' Husayn F. al-Hamdani (1901-1962) writes in his 'On the Genealogy of Fatimid Caliphs'(Cairo, 1958, p. 18) that, 'It is likely that Muhammad b. Ismail, who did not, and could not, according to accounts, live a settled life at one place, went underground during his wanderings by assuming the name of Maymun.'
Before biding goodbye to his ancestral abode, Medina, Muhammad had secretly convened an assembly of his dais, inviting them from all the regions. When caliph Harun ar-Rashid came to know the secret assembly, he resolved to arrest Muhammad bin Ismail in Medina. In the meantime, Zubeda, the wife of Harun ar-Rashid and a secret follower of the Imam, managed to send her trusted servant towards the Imam in Medina, informing him the plan of the caliph. Thus, Muhammad bin Ismail had to make his footing out of Medina at once.
Tradition however has it that Muhammad first went to southern Iraq, where he acquired the epithet of al-maktum (veiled one), and then at Nishapur in disguise, where he lodged for some times. Nishapur was one of the most important of the four great cities of Khorasan. The word 'Nishapur' is derived from New-Shapur. In Armenian it is called Niu-Shapuh, then became Nishwpur, finally Nishapur. It is situated on the east side of a plain surrounded by hills. To the north and east of the town lies the ridge of Binalud-Kuh, which separates it from the valley of Mashhad and Tus. It was divided into 42 wards, 1 farsakh in length and breath. Muhammad afterwards proceeded towards Ray (the ancient Ragha), a town in Media, about 15 miles from Tehran. Ray was situated in the fertile zone which lies between the mountains and the desert. The Abbasids rebuilt and surrounded it by a ditch. Harun ar-Rashid was also born in Ray and used often to recall with pleasure his native town. In 195/810, caliph Mamun's general Tahir bin Hussain won a victory over caliph Amin's troops near Ray.
Ishaq bin al-Abbas al-Farsi, the Abbasid governor of Ray privily professed Ismaili doctrines. Muhammad betrothed to Fatima, the daughter of Sarah, sister of Ishaq bin al-Abbas; who gave birth to a son, who was named Abdullah, also known as Wafi Ahmad. When the news of Muhammad bin Ismail's stay at Ray reached the ears of Harun ar-Rashid, he wrote to Ishaq bin al-Abbas, ordering to arrest Muhammad and send him to Baghdad. Upon receipt of caliph's letter, he showed it to the Imam and replied to the caliph that he found no trace of Muhammad, and would send as soon as he was arrested, and thus he tried to put the caliph off the scent. But the spies planted by Baghdad were vigilants and reported to the caliph that Muhammad bin Ismail not only was living at governor's house, but that he was directing his mission from there. Upon this, the caliph wrote another letter to Ishaq bin al-Abbas, impugning him to come in person with his forces if his orders were not obeyed forthwith. The governor however made his usual reply.
Meanwhile, the complaints about Ali bin Musa bin Mahan, the governor of Khorasan reached the point where Harun ar-Rashid could no longer ignore them. With the intention of deposing his governor and to make a search of the Ismaili Imam, Harun ar-Rashid adopted a militant stance. In 189/805, he marched towards Ray with a detachment of his army, and after searching for the Imam through a tracking party, ordered the arrest and torture of Ishaq bin al-Abbas. He however did not give away any clue of the whereabouts of the Imam. Ishaq died as a result of severe and cruel torture that was inflicted upon him, and was rigorously flogged till death. He did not waver and stood firm in spite of excruciating tortures. In spite of the gloomy situation, however, his faith remained unshakable.
Muhammad selected Hurmuz as a chief dai of the mission, and then had made his footing at the fortified city of Nihawand, where he stayed with the governor, Mansur bin Jowshan, who had close ties with Ishaq bin al-Abbas. He allotted the Imam a piece of land in the district of Sarha, where he led a peaceful living.
Nihawand was a town, lying about forty miles south of old province of Hamdan. It lies on the southern road, which coming from Kirmanshah, leads into Ispahan. The district of Nihawand was formerly called Mah-Bahrajan or Maha-Dinar. Among the products of Nihawand the Arab historians mention willow-wood which was used for polo-sticks (sawalija), aromatic reeds (kasbat al-dharira) to be used for hanut (a kind of perfume).
It is related that Muhammad was traced out on one day in Sarha by the Abbasid agent, named Muhammad bin Ali al-Khorasani, who surprised the Imam in a mosque. He was greatly impressed to behold the Imam, and lost courage to arrest him, and permitted the Imam to escape. Thence, Muhammad went to Azar in Khuzistan, a province of south-western Iran. It was bounded on the west by the Iran-Iraq border; on the north by Luristan, on the south by the Persian Gulf; and on the east by the river Hindiyan. Muhammad thence proceeded to Shapur. Disguised as a merchant, he stayed in Shapur with a certain Qamas bin Nuh, whose daughter Rabta, he married. Shapur (Arabic Sabur), the Shapurgird of Firdusi; became an unscathed place for the Imam for some times.
When the Abbasids intensified their search for the Ismaili Imam to its extreme, Muhammad had to travel out of Iran and reached as far as the valley of Farghana, which was a large, prosperous and pleasant region. Farghana was known as the "Gate of Turkistan" and now it is in Uzbekistan and partly in Tajikistan. It must be however noted that the history of Tajikistan is bound up with that of Uzbekistan in Central Asia, for the two countries are not only contiguous, but have often been governed by the same rulers and subject to the same invasions. The dominant tradition has it that Muhammad bin Ismail had taken refuge at Farghana valley, situated mainly in the eastern Uzbekistan and partly in Tajikistan and Kyrgstan, covering an area of 8500 sq. miles. The old city of Faghana, however, is in Uzbekistan, spread over 2750 sq. miles with ancient ruins, wherefrom Muhammad bin Ismail seems to have dispatched his dais in the Pamir, the highland region of Central Asia, which is centered in the Gorno-Badakhshan in Tajikistan.
It is necessary here to remark that the Ismailis in upper Oxus were reportedly deep-rooted in their faith, but unfortunately we do not have details of the Ismaili mission during the veiled era in Central Asia. These Ismailis however retained a specific literary tradition by preserving and transmitting from generation to generation an anonymous treatise, entitled "Ummu'l-Kitab" that had certainly exercised a sole source of their religious inspiration for about three hundred years till the arrival of Nasir Khusaro in this region.
"Ummu'l-Kitab" consists of the discourses of Imam Muhammad al-Bakir in response of his disciples and the famous narrators of the traditions, such as Jabir bin Abdullah Ansari, Jabir al-Jufi and Muhammad bin al-Mufazzal bin Umar. It was composed originally in Arabic and was translated into Persian in later period. W. Ivanow assigns its compilation before the beginning of the 5th/11th century, while Henry Corbin (1903-1978) places its origin in 2nd/8th century.
"Ummu'l-Kitab" remained wrapped in mist for a long period. In 1898, A. Polovtsev, a Russian official in Turkistan, who was interested in the study of Ismailism and later became the Russian Consul-General in Bombay, while visiting the upper Oxus, he discovered a copy of "Ummu'l-Kitab". In 1911, its another Persian version was unearthed from Wakhan by the Russian official, called J. Lutsch. The photocopies of both these manuscripts were deposited in the Asiatic Museum of the Imperial Russian Academy of Science at St. Peterburg. Carl Salemann, the director of the Museum was editing its text, but his death in 1916 prevented the task. Later on, W. Ivanow was destined to edit and publish the text of "Ummu'l-Kitab" in 1936. He however based his edition on the copy which was obtained by Ivan I. Zarubin (1887-1964) in 1914 at Shagnan. "Ummu'l-Kitab" is a volume of 210 pages and was also translated into Italian by Pio Filippani- Ronconi in 1966 from Naples.
After some times, Muhammad returned to his ancestral abode, Salamia and died in 197/813. He left behind six sons, viz. Jafar, Ismail, Ahmad, Ali, Hussain and Abdullah. He had also a son named Yahya.
The word dawa (pl. du'at) is derived from du'a means to call, invite or summon, and thus the term dai denotes, 'he who summons', whose corresponding term in English is 'missionary' (derived from the Latin, mittere). The word dawa is also used in the sense of prayers, such as dawat al-mazlum (prayer of the oppressed), or dawa bi'l shifa (prayer of the health). The word dawat virtually originated in the time of Imam Jafar Sadik, and Abdullah bin Maymun had founded the Ismaili dawa organisation in Basra.
T.W. Arnold writes in 'The Preaching of Islam' (Aligarh, 1896, p. 277) that, 'The Ismailis were the master of organisation and tactics at the time of Abdullah bin Maymun.' W. Ivanow writes in 'Collectanea' (Holland, 1948, p. 20) that, 'The only branch of Islam in which the preaching of religion, dawat, was not only organised but even considered of special importance, was Ismailism.' According to 'The Encyclopaedia of Islam' (Leiden, 1965, 2nd vol., p. 168), 'The word dawat is well known as applied to the wide-spread Ismaili propaganda movement, appealing to Muslims to give their allegiance to an Imam descended from Ismail bin Jafar Sadik.'
Soon afterwards, Salamia became the headquarters of Ismaili dawat after Basra, while Yamen later on became the dai generating hub. Indeed, very little is known about the actual mission (dawa) system of early Ismailism, but it is however certain that the Ismaili mission was brisk and pervasive throughout the Islamic regions. In the broadest terms, it seems that Muhammad bin Ismail was represented by twelve hujjats in different regions, and beneath the hujjats, a hierarchy of missionaries (dais) conducted the different tasks of initiation and instruction. The Ismaili dais stimulated a network of the mission in many parts of the Abbasid empire and there was plenty of its activity even outside it. They fully exploited the socio-economic conditions of the weaker sections of society to attract them towards the mission on one hand, and the philosophical interpretations of the teachings of Islam to attract the thinking sections of the society on the other.
For purposes of mission, the world was divided into twelve parts, each being called jazira (usually translated as an island), known as the island of the earth (jazira al-arad). It is difficult to say whether jazira really meant an island. One can broadly agree with W.Ivanow when he says: 'It appears that in this sense jazira does not mean the island, as it usually means, but is taken here in its basic sense, from the root j-z-r = to cut off, and therefore means a slice, cutting, or a part, a section. Therefore the expression 12 jazair should be translated as the 12 sections of the world population. They are: Arabs, Turks, Berbars, Negroes, Abyssinians, Khazras, China, Daylam, Rum and Saqaliba. Thus this classification is partly based on geographical, and partly on ethnographical principle, and plainly belongs to the fourth/tenth century.' (vide 'The Rise of the Fatimids', Calcutta, 1942, p. 21)
Most of the adherents of Ismaili faith during the period under review are hardly known due to the practice of taqiya. But, the Ismaili dais had best records of it, who became the source of informations for the later Ismaili authorities. Among the secret followers, the name of Zubaida, the wife of caliph Harun ar-Rashid is a significant. She was the daughter of the Abbasid caliph Mansur's elder son, Jafar; and her mother was Salsal, the sister of Harun ar-Rashid's own mother, named Khaizuran. Zubaida was thus the cousin of Harun ar-Rashid, and professed batini tariqah of the Ismailis secretly. Her marriage with Harun ar-Rashid took place in 164/781. Zubaida, in middle life, built herself a palace of her own, surrounded by a very large garden. She had employed a large staff of secretaries and agents to manage the properties she had acquired in all over the empire. She also undertook projects for the digging of canals for irrigation and water supply. She was famous for the extensive engineering works which she had carried out in Mecca, to bring water sufficient for the increasing number of pilgrims. One of the most of her projects was the improvement of the pilgrim road across 900 miles of desert from Kufa to Medina and Mecca, which still in south Kufa is known as Darb Zubaida. She died in 226/841, about 32 years after her husband's death. It appears that she advocated Ismaili faith before her marriage in 164/781 and used to inform Imam Muhammad bin Ismail in advance the measures of Harun ar-Rashid through her trusted agents. It also appears that her close link with the Imam had ceased after the death of Muhammad bin Ismail.
According to 'Zahru'l-ma'ani', 'Muhammad spread religious knowledge, explained esoteric doctrines, and revealed to the chosen ones the great mystery, so much of these as never was revealed by any Imam before him.'
Some sources state that after the massacre of Abul Khattab and his followers in Kufa, the remnants joined al-Mubarakiyya, and that out of this union arose a group who preached that Muhammad bin Ismail was the last Imam, anticipating his return. It was however this group who was the predecessors of the later Qarmatians, who refused to accept the death of Muhammad bin Ismail, who, according to them remained alive and would return in the imminent future as the promised Mahdi or Qaim. The main loyalist branch of Ismailism however traced the Imamate in the progeny of Muhammad bin Ismail.
The period of Muhammad bin Ismail also saw an early growth of the Sufism in Islam. The eminent Sufis who flourished in the period under review were Hasan Basri (d. 110/728), Ibrahim bin Adham (d. 160/776), Abu Hashim Kufi (d. 160/775-6), Rabia Basri (d. 185/801), Shaqiq Balkhi (d. 194/810), etc.
It is worth mentioning that the Sunni historians had no basic idea of the Shiite concept of Imamate and arrayed hostility with the Ismailis in the light of their own sense of propriety. They championed in dressing up the baseless stories in their notion, and then used it a tool to defile Ismailism in aggressive and hyperbolic words. Under such derogatory attitude, Muhammad bin Ismail is accused of claiming the prophethood and abolishing the Shariah of the Prophet.
The institution of the Imamate is a cornerstone and paramount position in Ismaili tariqah, and according to their theory, the seven millennial periods (adwar'i azam) form a part of a great cycle of 360,000 years. At its end, during the last period of 7000 years, there were six natiqs (speakers, pronouncers or law-givers), viz. Adam, Noah, Abraham, Moses, Jesus and Muhammad, the last Prophet. They are the seven law-givers. Each great period is started by the introduction of a new religion. This religion, exercising great influence upon mankind at the outset, but lost its original force with the passage of time. It is ultimately replaced by a new system to retain its originality and make it forceful then onwards. Each natiq lays down the Shariah for his period, and appoints an asas (base, foundation or executor). The asas lays the foundation of hidden knowledge (ilm al-batin), who is also called wasi, organizing the dissemination of the hidden knowledge among the faithfuls only. The asas is followed by a chain of Imams, who stimulate the mission on the basis of hidden teachings. The period (dawr) of one natiq comprises six ones and the seventh one becomes another natiq, who either proclaims another Shariah setting aside the earlier one, or cancelling (tatil al-shariah) its manifestation, and gives it a new interpretation on the ground of hidden secrets (asrar'i batin). The Prophet Muhammad was preceded by five natiqs, each natiq had cancelled his predecessor's Shariah. With this cycle, the Prophet stands as the sixth natiq who appointed his son-in-law Ali as his wasi, and there followed after him six Imams, bringing the Prophet's period (dawr) to a close. The seventh Imam, Muhammad bin Ismail was the seventh natiq in the new heptad. Muhammad Bakir Majlisi quotes a Hadith in his 'Biharu'l Anwar' (13th vol., p. 156) that, 'The next expected (natiq) Imam would be 'the son of six' (ibn sitta), means the next natiq would be preceded by six Imams.' Since there was no Shariahafter the Prophet, Muhammad bin Ismail was not to announce a new religious law. Instead, he would reveal the esoteric truths concealed behind all the preceding messages. He abrogated the adulterated parts of the Shariah by explaining the hidden meaning of the true Shariah and revealing its purpose. The Islamic Shariah had lost much of its pristine purity, and many unhealthy practices crept into the religion, therefore, the tawil was applied to protect its dynamic force.
Abrogation of the Shariah, therefore, by every seventh natiq encompasses the meaning of the law only, not its exoteric or practical and ritualistic aspects. The Prophet was ar-Rasulu'n-Natiq, whereas Muhammad bin Ismail was al-Imamu'n-Natiq. The former was the natiq in the capacity of the Prophethood, and the latter was the natiq in the role of Imamate. Thus, Muhammad bin Ismail had never repudiated or suspended the Shariah for his followers. Arif Tamir writes in 'al-Qaramita' (pp. 86-87) that, 'The Imamate of Muhammad bin Ismail was the beginning of a new era in the history of the Ismaili movement. We go even further to say that he came with some new teachings, setting aside some exoteric teachings which preceded. He was in fact the first Imam to have done away with the trouble of manifestation and gave call for tawil and esoteric meaning, and for spreading his mission, he relied on his hujjat and great dai, Maymun al-Qaddah.' Idris Imaduddin (d. 872/1468) writes in 'Zahru'l-ma'ani' that, 'Muhammad bin Ismail was named the seventh natiq, because he rose to preach by the command of God, incorporating in himself all the virtues which are to be crowned in him. He is neither the Revealer of the final religion, nor the Apostle of God, but he is in a class by himself, of a unique rank.'
It must be noted that the period of Muhammad bin Ismail was a turning point in the history of the Ismaili mission. The Abbasids revolution had been consolidated, and the Iranian influence in particular and Greek influence in general were being applied in the intellectual field. In a century that followed, the wave of Muslim conquest reached upto Samarkand, beyond the Oxus. With the extension of Muslim territory, there cropped up a number of new problems neither contained in Koran, nor anticipated by the Prophet. Hundreds of schools of jurisprudence appeared to mould the Muslim system of laws, but none could crystallize into definite system, acceptable by all. 'Some five hundred schools of jurisprudence' writes Adam Mez in 'The Renaissance of Islam' (London, 1937, p. 212), 'are said to have disappeared at or about the beginning of the 3rd/9th century.'
The Schools of Law represented by Abu Hanifah (d. 150/767), Malik bin Anas (d. 179/795), al-Shafi (d. 204/819) and Ahmad bin Hanbal (d. 241/855) also emerged prominently in this period. The major collections of Hadiths also were done mainly by Bukhari (d. 256/870) and Muslim bin al-Hajjaj (d. 261/875).
The problem however was to find a correct balance among all these developments when the Islamic world was undergoing radical changes. Islam had to keep pace with, and adjust to, the fast changing world and the growing of new trend. Muhammad bin Ismail had to impart the true Islamic teachings through tawil (the allegorical interpretation) based on reason to his followers. It was thus absolutely a false propaganda of the historians that Muhammad bin Ismail - he being the seventh natiq had claimed for his apostleship or cancelled the Shariah of the Prophet. P.J. Vatikiotis writes in 'The Fatimid Theory of State' (Lahore, 1957, p. 90) that, 'Abrogation of the Shariahby every Seventh natiq, as for example Muhammad b. Ismail, encompasses the meaning of the law only, not its zahir or practical and ritualistic aspect. Muhammad b. Ismail did not abolish anything of the formal worship and law of the Shariah; on the contrary, he strengthened it, and ordered everyone to act according to it. What Imam al-Muizz meant by the expression al-shariah uttilat, or the Shariah of Muhammad was purified by his mission, refers to his explaining its meaning and clarifying its hidden points. Tatil of Shariah, then, means its purification through tawil. A revelation of the external truths behind the Shariah to the closest initiates in the dawa constitutes Fatimid abrogation of law. It is not an abrogation that overthrows accepted legal ritual in the Quran, but rather the reconciliation of such law with religious philosophy.'
It should also be known that the mis-interpretation of the theory of Muhammad bin Ismail as the Seventh natiq by the Sunni historians had engendered the coinage of the name 'Seveners' (sabiya) for the Ismailis, which is a glaring instance, sounding their misconception in the Ismaili belief of Imamate. The Muslim knowledge of the Ismailis in the field of tawil had not progressed much beyond what they had transmitted on the subject. They knew little and broadcast more, and the field therefore continued to be dominated by the fanciful impressions and fictitious hodgepodge.
