While the notion of philosophical hermeneutics and its impact on discourses of Islamic law and ethics have been a continuous feature of comparative and religious study in the recent past, this has tended to take the form of theoretical and largely textual hermeneutical readings. This article aims to examine the instances of the occurrence of one particular aspect of the philosophical hermeneutical canon, the Gadamerian notion of horizontverschmelzung, within the work of the contemporary Islamic legal thinker, Khaled Abou El Fadl. In doing so, the article focuses on the way in which the notion of horizontverschmelzung is used by Khaled Abou El Fadl both explicitly, in his textual work, and implicitly, in the performance of his broader methodological project. This dual dynamic is made apparent in his work that aims to engage with debates that are internal to the Muslim community, such as those over the process of the interpretation of the Shari'a, and those that involve the Muslim community's relationship with the West, such as those to do with representation and identity. This dynamic is a vital consideration for the further understanding of contemporary forms of philosophical hermeneutics in the islamicate context and the legal and social work of Khaled Abou El Fadl.
