Thanks to the pioneering and lifelong studies by Paul Walker, we are becoming increasingly knowledgeable about the Fatimid daՙi and philosopher Abu Yaՙqub al-Sijistani. Based on two manuscripts, Dr. Boustan Hirji has prepared an English translation and critical edition of the Arabic text of Yaqub al-Sijistani’s al-Risalah al-Bahirah (‘The Epistle on the Radiance‘).



The book originated as a doctoral dissertation at McGill University under Professor Hermann Landolt, who served as Senior Research Fellow and member of the Editorial Board of the Institute of Ismaili Studies. The publication will appeal to all who are interested in Fatimid philosophy in general and al-Sijistani’s philosophy in particular including academic students and scholars as well as members of the Jamat and the general public.
In his extended Foreword to the book, Mohamed Abualy Alibhai sketches a conceptual framework in which the significance of Dr. Hirji’s exemplary study is recognized, appreciated, and acknowledged.
