Abbas Shah, surnamed Shah Gharib or Gharib Mirza, was also known as Gharibu'l-lah and Mustansir billah III, and assumed the Imamate in 899/1493.
Gharib Mirza seems to have left Shahr-i Babak few months after assuming Imamate. He seems to have repaired for about one year out of Shahr-i Babak, leaving behind his hujjat, called Badiuddin Khwaja Kassim, and at length settled down in Anjudan, most possibly in 900/1494. Pir Shihabuddin Shah (d. 1884) also writes in his 'Khitabat-i Aliyya' (pp. 42-43) that, ' The thirty-fourth Imam Abbas Shah (Gharib Mirza) was obliged to live for some time away from his ancestral home (watn-i maluf), i.e., Shahr-i Babak.' The reason of his absence was that the rambling bands of Chaghatays and Turkomans had once again gushed from Jurjan and Tabaristan after being supressed in 883/1478 by the Ak-Koynunlu commander, Sufi Khalil Beg. They plundered the surrounding localities of Kirman and Sirjan.
Anjudan (Injodan or Anjidan) is situated at the foot of relatively low rocky range, about 37 kilometers east of Arak (former Sultanabad) and about the same distance westward from Mahallat in central Iran. It is separated 35-40 kilometers with Kahek by a number of shallow ranges, and is also close to Qumm and Kashan. The Ismailis had begun their settlements slowly in Anjudan most probably during the time of Imam Mustansir billah II, and had taken there agriculture. It was the cradle land of the Ismaili mission in post-Alamut era. The Syrian Ismailis called Anjudan as 'the abode of the faithfuls' (dar al-mominin). It was simply walled to protect the populace in times of insecurity.
Gharib Mirza at length shifted to Anjudan and kept himself completely out of the vortex of politics, and passed a life of darwish, where he became known as Gharib Mirza i.e., 'an unknown stranger.' Earlier, he was generally known as Abbas Shah. He also applied the name Gharib Mirza in his writing in Anjudan. His eloquent power was impressive and sweet, and was highly respected among the local non-Ismaili orbits. He was a man of affable temperament and wide human sympathies which made him a popular figure in the locality. An anonymous manuscript dating about 1196/1782 cites the anecdote of a certain peasant, whom the Imam had gifted a piece of land in Shahr-i Babak, who in turn said, 'Sayed Gharib Shah is a generous like his ancestor, Imam Jafar Sadik.' He thus had set an example to the local people by an act of humanity and generosity which created a salutary effect upon his fellow-citizens.
It appears that the dawa system after the fall of Alamut was organised systematically in Anjudan period. According to the new system, the Imam was followed by a single hujjat, known as hujjat-i azam (the great proof), who generally resided at headquarters. The hujjat administered the framework of the mission and served as an assistant of the Imam. Next, there was a single category of dai at large, being selected from among the educated classes. The dais remained close in contact with the headquarters. The next lower rank was that of mu'allim (teacher), the head of the mission activities in a particular region. He was appointed by the hujjat. He was further assisted by ma'dhum-i akbar (the senior licentiate), who was empowered to make conversion at his disposal and judgement. Another assistant of the mu'allim was called ma'dhum-i asghar (junior licentiate), who held the lowest rank and could discharge his assignments only on receiving official permission from the mu'allim. The ordinary initiates (murids) were referred to as mustajib (respondent). On acquiring adequate training, a mustajib could be appointed by the mu'allim to the rank of ma'dhum-i asghar. It must be remembered that the aforesaid mission system was enforced in Iran, Badakhshan and Central Asia. In Hind and Sind, the tradition of the vakilhad been retained, corresponding to the office of the mu'allim.
In Central Asia, the ma'dhum-i akbar gradually became known as the pir, and ma'dhum-i asghar was known as khalifa. They stressed on the practice of zikr-i jalli, recitation of the qasida and the esoteric poems of Nasir Khusaro among the new converts.
In addition, the Ismailis held that the true essence of the Imam could be known at least to a few advanced followers in the community, and the hujjator the pir was, indeed, held to be almost the same essence as the Imam. Hence, the hujjat or pir, by virtue of his miraculous knowledge (mu'jiz-i ilmi), knew the true essence of the Imam, and was the revealer of the spiritual truth. Furthermore, the Ismailis recognized three categories of people in the world. Firstly, the opponents of the Imam (ahl-i tadadd). Secondly, the ordinary followers of the Imam (ahl-i tarattub), also known as ahl-i haq, who were also divided into the strong (qawiyan), comprised of the dais, mu'allims and ma'dhums, and the weak (da'ifan), restricted to the ordinary members of the community. Thirdly, the followers of union (ahl-i wahda), also called as the high elite (akhass-i khass).
The Safavid family was active in making ground to emerge as a new power in Iran, tracing descent from Musa Kazim. The prominent head at that time was Shaikh Safi, or Safiuddin Abul Fath Ishaq Ardabili (1252-1334), who founded a Sufi order, known after him as the Safaviya at Ardabil in Azerbaijan. He died in 735/1334 and his order was continued by his son, Sadruddin Musa (1334-1391), and then by another son, Khwaja Ali (1391-1427). They deeply influenced most of the Mongol rulers and amirs. Ibrahim (1427-1447), the son of Khwaja Ali also continued the Sufi order founded by Shaikh Safi, but Junayd (1447-1460), the son of Ibrahim acquired some political power and introduced the doctrines of the Twelvers at the time of his death in 1460. He fought several times with the rulers of Kara-Koyunlu, but was killed at Shirwan. His followers continued to gain religious and political leads in Iran. Junayd's son married to Martha, a Greek princess, who bore Sultan Ali, Ibrahim and Ismail. His another son, Hyder (1460-1478) was killed, and other sons were arrested. Thus, only Ismail was survived, because Sultan Ali was also killed and Ibrahim had died very soon. Hence, the events continued to boost the rising of the Safavids during the time of Ismail. Gilan was the centre of the Safavid family. Ismail collected a small force and occupied Baku and Shamakha. He defeated Alwand, the prince of Ak-Kuyunlu dynasty, and captured Tabriz. He also inflicted defeat to the Mongolian ruler and was proclaimed as Shah Ismail and founded the Safavid dynasty in 905/1500 in Iran.
Nuruddin Shah, the younger brother of Gharib Mirza is said to have built a small village near Anjudan after his name, called Nurabad. He also built a defensive post and few small buildings. He erected a Sufi khanqah (cloister) of Abbas Shahi tradition for the local Sufis.
The Ismailis had continued their flocking at Anjudan, where Gharib Mirza confessed their offerings and blessed them with written guidances, bearing his signature and seal. It has since become a tradition in India to celebrate the day of rejoice with great pomp by commonalty and gentry alike when the pilgrims returned unscathed to their homeland.
While examining the traditions congealed around the adherents, it appears that the Ismaili history abounds with the instances of great sacrifices of the daring devotees. For illustration, a best-known Syrian tradition relates a touching anecdote that once a caravan embarked from Khwabi for Anjudan to see Gharib Mirza. At that time, the Safavids were emerging in Iran, therefore, the routes were insecure and the time was not ideal for travellers. When Gharib Mirza knew about the arriving caravan from Syria, he decided to send them back. The time was so critical that no messenger could carry any written order with him. Gharib Mirza at once sought the service of a fidai, who was made lain on the ground without a shirt. Imam got his official orders carved by a dagger on backside of his body with the help of a servant, addressing the Syrian Ismailis to return back at once. The heated copper seal of the Imam was stamped at the concluding part. The young fidai tolerated the pain patiently, and put on a black shirt. He spurred his horse at full gallop for an errand being fraught with danger and gave an ostensible impression of an ordinary man to the people. He succeeded to reach the caravan, whom he transmitted the Imam's orders verbally at first. When he was asked its veracity, he took off his shirt, stuck with the congealed blood, and turned around and made them read the orders of the Imam carved on his backside that, 'la ta'tu hazi'his sanh wa lakin fis sanh'til qadema la bud'd alaikum an ta'tu' i.e., 'you do not come this year, and come next year.' Looking the fidai who displayed a rare prodigies example of valour at great risk, tears welled up in their eyes and returned back soon with sad hearts.
Abu Ishaq Kohistani was a learned dai around this period. His name was Ibrahim, was from the district of Mominabad-i Kohistan in the province of Birjand. Nothing is known about his activities. He was however a writer, and it appears from his writings that he had studied the accessible literature of Alamut period. His famous work, 'Haft Bab-i Bu Ishaq' deals the recognition of the Imam with philosophical arguments on Ismaili tariqah. His another work, 'Tarikh-i Kohistan' is not traceable.
It is related that Gharib Mirza mastered the botanical field, and with his knowledge, the village of Anjudan was turned into a fertile tract. He mostly passed his whole life in Anjudan, and died in 902/1496. In Anjudan, near the mausoleum of Imam Mustansir billah II, there exists an old burial ground in the garden, the middle of which stands the mausoleum of Gharib Mirza. The wooden box (sanduq) contains Sura Yasin of Holy Koran. In one place, it is clearly written:- 'This is the wooden box (sanduq) of Shah Mustansir billah (i.e., Gharib Mirza), the son of Shah Abdus Salam. Written on the 10th of Muharram, 904/August 29, 1498.' From this one can conclude that this wooden box was erected about two years after the death of Imam Gharib Mirza.
