Apologetic Arguments in Ṣāliḥ ibn al-Ḥusayn al-Jaʿfarī’s Kitāb al-radd ʿalā al-Naṣārā

ABSTRACT Medieval Muslim scholars wrote substantial apologetic and polemical treatises to present and defend the truth of their religion and to invite people of different faiths to Islam. These texts belong to the so-called radd (‘refutation’) literature. It is still interesting today in so far as many radd authors avoided rhetorical polemics and sought serious rational arguments that provide deep insights in the dogmatic differences and peculiarities of various religions. An outstanding, because strongly argumentational, example is Kitāb al-radd ʿalā al-Naṣārā (‘Book of refutation of the Christians’) by Ṣāliḥ ibn al-Ḥusayn al-Jaʿfarī (d. 668/1270). This article introduces al-Jaʿfarī’s life and work, outlines methodological premises for a critical analysis of radd arguments, gives an overview of al-Jaʿfarī’s most important arguments and an example of the analysis of such arguments, and indicates what the examination of these old texts can contribute to today’s interreligious discourses.
