Sind was also the scene of the labours of Pīr Ṣadr al-Dīn, an Ismāʻīlī missionary, who was head of the Khojah sect about the year 1430. In accordance with the principles of accommodation practised by this sect, he took a Hindu name and made certain concessions to the religious beliefs of the Hindus whose conversion he sought to achieve, and introduced among them a book entitled Dasavatār in which ʻAlī was made out to be the tenth Avatār or incarnation of Viṣṇu; this book has been from the beginning the accepted scripture of the Khojah sect, and it is always read by the bedside of the dying and periodically at many festivals; it assumes the nine incarnations of Viṣṇu to be true as far as they go, but to fall short of the perfect truth, and supplements this imperfect Vaiṣṇav system by the cardinal doctrine of the Ismāʻīlians, the incarnation and coming manifestation of ʻAlī. Further, he made out Brahmā to be Muḥammad, Viṣṇu to be ʻAlī and Adam Siva. The first of Pīr Ṣadr al-Dīn’s converts were won in the villages and towns of Upper Sind: he preached also in Cutch and from these parts the doctrines of this sect spread southwards through Gujarāt to Bombay; and at the present day Khojah communities are to be found in almost all the large trading towns of Western India and on the seaboard of the Indian Ocean. [898] Pīr Ṣadr al-Dīn was not however the first of the Ismāʻīlian missionaries who came into India. He was preceded by ʻAbd Allāh, a missionary sent from Yaman about 1067; he is said to have been a man of great learning, and is credited with the performance of many miracles, whereby he convinced a large number of Hindus of the truth of his religion. [899] The second Ismāʻīlī missionary, Nūr al-Dīn, generally known by the Hindu name he adopted, Nūr Satāgar, was sent into India from Alamūt, the stronghold of the Grand Master of the Ismāʻīlīs, and reached Gujarāt in the reign of the Hindu king, Siddhā Rāj (A.D. 1094–1143). [900] He adopted a Hindu name but told the Muhammadans that his real name was Sayyid Saʻādat; he is said to have converted the Kanbīs, Khārwās and Korīs, low castes of Gujarāt. [901]
