Hasan Ali Khan, Shia-Ismaili Motifs in the Sufi Architecture of the Indus Valley, 1200-1500 A.D., PhD thesis in Religious Studies, SOAS, London, 30 April 2009.
“The relationship between Shiism and Sufism is one of the most unexplored areas of Islamic studies. Its study has traditionally been hindered by the lack of primary sources. This is especially so in the case of Ismailism in the medieval Islamic Era, which is more easily associable to Sufism.
Ismaili associations with early Sufism go back to the Fatimid Era in Egypt of which the Indus Valley was a part. This is in the tenth century when dominant Ismaili and Twelver states ruled the Middle East. After the destruction of these Shia states by the incoming Sunni Turkic dynasties, Ismailism went underground in Iran and its ideas reappeared in the shape of Sufi Orders in Iraq, most prominently the Suhrawardi Order. In this period, Ismailism flourished again in the Indus Valley under missionaries sent from neighboring Iran, who freely worked on the metaphysical commonality between Indian and Iranian cultures for their proselytism. Its zenith was reached under the Ismaili missionary Shams in the thirteenth century, who after a long spate of problems in his host country, perfected a system of metaphysical interlacing called the Satpanth, or true path, setting up ceremonies which tied him to the Suhrawardi Sufi Order which preexisted here. This association led to the falling out of the court patronised order with the Imperial Authorities in Delhi. The Satpanth worked through an astrological framework based on the Persian New Year, and the vice-regency of the first Shia Imam Ali, which is the basis of the Shia faith. The astrological resonances of Ali’s succession or vice-regency to Muhammad were known to Muslim scholars in the Iranian Shia-Ismaili tradition before Shams’s time, but are historically first interlaced by Shams with the local calendar for the benefit of his followers. The Satpanth later found its way as astrological symbolism on the monuments of the Suhrawardi Order. In addition, an unorthodox monument archetype which accommodates Satpanth ideals is common to the buildings associated with Shams, his descendants and Suhrawardi Sufis over three centuries. Evidence suggest that Shams may have been responsible this archetype.
A comparison between extant religious ceremony, iconography and the common monument archetype in the latter chapters shows the covert Shia-Ismaili beliefs of the Suhrawardi Order in the Indus Valley. This complements the critical reexamination of historical sources for the purpose in the first half of the thesis.”
