Naṣīr Khusraw was a leading Ismaili poet and theologian-philosopher of the eleventh century. His writings have had a major formative influence on the Ismaili Muslim communities of Iran, Afghanistan and Tajikistan. The bulk of his surviving work was produced in exile in a mountainous region of Badakhshan, where he sought refuge from persecution in his native district of Balkh.

This is a new edition and English translation of Naṣīr Khusraw’s Gushāyish wa Rahāyish. It is the first major treatise by him to be translated into English. Consisting of a series of thirty questions and answers, it addresses some of the central philosophical and theological issues of his time from an Ismaili perspective, ranging from the creation of the world and the nature of the soul to the questions of human free will and responsibility.
