This chapter explores the rich and underexamined tradition of adāb al-qabr—Islamic literature on the salvific terrors of the grave—through a semiotic lens. Beginning with scriptural sources from the Qur’an and ḥadīth, it examines how Arab-Muslim narratives conceptualize the dead as paradoxical beings—simultaneously lifeless and communicative. Drawing on exegetical traditions and popular texts, the study shows how the grave is depicted as a spatial and symbolic threshold between life and the afterlife, where bodies are interrogated, punished, or rewarded. The chapter analyzes key figures such as the angels Nakīr and Munkar, whose roles construct intersubjectivity for the dead and enable narrative continuity. Through tropes such as dreams, testimonies, and Qur’anic intercession, these texts create a “possible world” governed by a unique reading pact based on divine authority, fear, and moral edification. The literature both affirms Islamic eschatology and cultivates imaginative engagement with the unseen. By interrogating how the genre negotiates the ontological contradiction of the living-dead body, the chapter opens a broader reflection on narration, authority, and the cultural production of terror. It concludes with a call for further interdisciplinary study of this vast corpus and its theological, rhetorical, and cultural implications.
