This paper focuses on Mālikite polymath Ibn Ẓafar al-Ṣiqillī (d. ca. 565/1170) and primarily, though not exclusively, on his Sulwān al-Muṯāʿ fī ʿAdwān al-Atbāʿ, a book that belongs to the literary genre of "Mirror for Princes" (ādāb al-mulūk) and that was written most likely during the 1150s. As far as the state of art is concerned, Kenneth Garden has recently reiterated that Ibn Ẓafar al-Ṣiqillī took an active part in the debate that arose after the spreading of al-Ġazālī's (d. 505/1111) Iḥyāʾ ʿŪlūm ad-Dīn by writing a book (to date considered lost) in which he defended al-Ġazālī from the attacks contained in al-Imām al-Māzārī's (d. 536/1141) al-Kašf wa-al-Anbāʾ. In addition to these books of refutation and counter-refutation, traces of pro/anti-Ġazālian debates can also be found in other fields, including the genre of ādāb al-mulūk. In this regard, by analyzing the content of al-Asad al-ġawwāṣ, an example of an early 6th/12th "Mirror for Princes", Frank Griffel identified the Ġazālian perspective of the unknown author, thus highlighting the cross-pollination between the debate on al-Ġazāli's legacy and this literary genre. In view of this connection, the paper focuses on the theological and philosophical elements that emerge in Sulwān al- Muṯāʿ fī ʿAdwān al-Atbāʿ in order to further investigate Ibn Ẓafar al-Ṣiqillī's positioning within the pro/anti-Ġazālian debate as well as to shed new light on Sunni political theory and its developments during 6th/12th century.
