Amid growing ideological plurality, liberal democracies face the critical challenge of fostering social cohesion among citizens through an ethics of citizenship, enabling them to engage in rationally motivated understanding rooted in civic solidarity when addressing matters of dispute. This requires that individuals with differing beliefs develop the capacity to adopt others' perspectives—a form of interreligious competence particularly vital when one's own religious beliefs and practices are questioned or challenged. This raises a central question: to what extent does religious self-understanding encourage or hinder religious citizens from participating in public processes of "democratic opinion- and will-formation" (Habermas)? This paper explores this question within the context of the Islamic faith tradition, focusing on selected Qur'anic passages that depict (imagined) dialogues with two distinct communities — Christians and Polytheists. Using a dual hermeneutic approach, it reconstructs patterns of argumentation within the examined Qur'anic passages, shedding light on how interreligious dialogue is conceptualized and exemplarily negotiated within the Qur'anic Weltanschauung. I argue that the Qur'an, in specific passages, demonstrates a remarkable effort to train its attentive readers to adopt the perspectives of people of other faiths - an insightful pedagogical endeavor that has largely been underestimated thus far. The extent to which this effort can be interpreted as a contribution to fostering social cohesion will be examined.
