Various models of interreligious relations have been proposed in recent scholarship, including most prominently the several varieties of inclusivism, exclusivism, and pluralism. One abiding presupposition shared across these models takes the religious adherent (or community of adherents), as a unified individual (or collective of such individuals). This seemingly unproblematic assumption overlooks an important feature of the certain prominent strains of religiosity which negate selfhood. This article seeks to apply such understandings of (non-)selfhood to interreligious relations, with particular focus on the theoretical elaborations of the Classical Islamic thinkers Abū Yazīd al-Bisṭamī (c. 804 – 874 CE), Abū l-Qāsem al-Junayd (830 – 910 CE), ʿAbd al-Karīm ibn Hawāzin al-Qushayrī (c. 986 – 1074 CE), Farīd al-Dīn ʿAṭṭār Nayshābūrī (c. 1142 – c. 1221 CE) and, Muḥyiddīn Ibn ʿArabī (1165 – 1240 CE).
