Da'i al-Du'at — the chief missionary

داعي الدعاة

The da'i al-du'at, the great official to whom the headship of the Ismaili da'wa was entrusted under the Fatimids: ranking just below the qadi al-qudat and wearing his dress, the two offices often held by one man. Twelve nuqaba' assisted him in spreading the doctrine and deputies represented him in the provinces — the link between caliph and adherents — administering the oath to initiates directly or by proxy and overseeing the lectures delivered in the majlis al-da'wa, which were submitted to the caliph for approval before being taught; he also collected the najwa of 'believing men and women' at three and a third dirhams, and whoever paid thirty-three dinars received a Fatimid chit bearing the caliph's signature.

Overview

Dai al-duat ("chief of the missionaries") was a senior office, entrusted with the leadership of the Ismaili mission under the Fatimids. 1

The office

Hasan Ibrahim Hasan notes that it ranked just below the chief judge (qadi al-qudat) and wore his dress, and that the two offices were often combined in one man. 1

Twelve naqibs assisted him in spreading the teachings, and he had deputies in the lands. He was thus the link between the caliph and his followers in the Ismaili mission. 1

His duties

  • Taking the oath of allegiance from novices, directly or through his deputies.
  • Supervising the lectures in the assembly of the mission, which were presented to the caliph before they were delivered.
  • Collecting the contributions (najwa) from the believing men and women, set at three dirhams and a third. Whoever paid thirty-three dinars was given a Fatimid badge, which was a slip bearing the caliph's signature.

Al-Azhar Mosque

Al-Azhar at Cairo: founded by the Fatimids as the mosque of their da'wa, then turned by the vizier Ya'qub ibn Killis in 378 into a university teaching the sciences and letters — from a pulpit reserved for the Fatimid call into one of Egypt's foremost centres of learning beside the mosques of Amr, Ibn Tulun and al-Hakim.
