The Ismaili dāʿī (missionary) and poet Nāṣir-i Khusraw (d. after 1070) wrote Khwān al-ikhwān (The Banquet of the Brethren) when he was living in his remote mountain refuge of Yumgan in Badakhshan. This work includes a précis of ideas found in the Kitāb al-Yanābīʿ (al-ḥikma) (The Wellsprings of Wisdom), written by the earlier dāʿī Abū Yaʿqūb al-Sijistānī (d. ca. 971). Nāṣir-i Khusraw recast these ideas in Persian and then expanded them into 100 chapters (or ‘courses’ of a banquet). The text presents a sequence of dynamic arguments for divine unicity (tawḥīd), while also asserting the authority of the Prophet Muhammad, his legatee and son-in-law ʿAlī b. Abī Ṭālib, and the subsequent Imams from the line of the Prophet’s descendant Ismāʿīl b. Jaʿfar al-Ṣādiq.

Khwān al-ikhwān stands as a significant work in Ismaili theology and philosophy, exemplifying the central role of taʾwīl (esoteric interpretation). It also reflects the learning of the age, including the conception of a geocentric cosmos, Aristotelian physics, and Neoplatonic philosophy, all of which profoundly influenced the Ismaili dāʿīs in Iran.

This new Persian critical edition is based on the only two extant manuscripts of Khwān al-ikhwān, while referring additionally to Henry Corbin’s edition of al-Sijistānī’s Kitāb al-Yanābīʿ. Rahim Gholami has also prepared an accompanying volume containing an annotated English translation of the Persian text.
