Abu Ya'qub al-Sijistani
? · Mecca
Abu Ya'qub Ishaq ibn Ahmad al-Sijistani (also called al-Sijzi) was a tenth-century thinker and missionary of Ismaili Shia Islam, a branch of Shi'ism that organized its preaching through a network called the da'wa ("the summons/mission"). His birth year is unknown; his name (nisba) points to origins in Sistan, in the eastern Iranian world. He worked as a da'i (missionary-teacher) across Khurasan and Transoxiana, regions then under Sunni Samanid rule, where Ismaili preaching was risky.
He is reported to have succeeded an earlier missionary, Muhammad al-Nasafi, both as a leading da'i and as a developer of his ideas. In his own writing he mentions being in Baghdad/Iraq in 934 (322 AH), having returned from the pilgrimage (hajj) to Mecca. Early in his career his movement preached independently of the Fatimid caliphs in North Africa; later, traditionally during the reign of the Fatimid imam al-Mu'izz (953–975), he came to accept the Fatimid imams.
His lasting importance is intellectual: he absorbed Neoplatonic philosophy into Ismaili thought, describing God as beyond both being and non-being, knowable only through a "double negation," and placing a single universal Intellect at the summit of creation. Works ascribed to him include Kashf al-mahjub ("Unveiling of the Hidden," surviving in Persian paraphrase), Kitab al-Yanabi' ("Wellsprings"), and Kitab al-iftikhar (composed around 971). The date and circumstances of his death are genuinely disputed: a late source (Rashid al-Din) reports he was executed by the Saffarid emir Khalaf ibn Ahmad, but other scholarship, noting that his works mention the Fatimid caliph al-Hakim (who acceded in 996), places his death considerably later — perhaps between 996 and 1003. No firm death year can be given.

Mecca
What they did here
In his own writing (Kitab al-iftikhar) al-Sijistani states he had returned from the pilgrimage to Mecca when he was in Baghdad/Iraq in 322/934. The hajj itself is an inference from this self-report; the precise year (c. 933) is reconstructed from the Baghdad date, not directly stated.
About Mecca
Mecca (Makka), in the Hejaz of western Saudi Arabia, is the birthplace of the Prophet Muhammad and the site of the Ka'ba; it is Islam's holiest city and the destination of the annual hajj pilgrimage, toward which Muslims pray. As a centre of learning that drew scholars from across the Muslim world, it hosted many of the figures connected here during periods of study, teaching, or pilgrimage.
