Salvation and Hell in Classical Islamic Thought uses classical Islamic sources to trace the development of Islamic eschatology during the formative centuries of Islamic intellectual history. Marco Demichelis draws on classical Islamic scholars, including Ibn Sina, al-Ghazali, Ibn Taymiyya, and Ibn Qayyim al-Jawziyya, to bring together concepts from Islamic philosophy, theology and mysticism – including proto-Sufism – to examine the interplay of these concepts between these traditions. The doctrines of salvation from Hell are examined in depth, in particular the theory of the annihilation of Hell, which proposes the idea that there will be a time when Hell will be empty and no longer inhabited. This is the first book to examine Islamic eschatology in the classical period, and adds to the growing scholarship on Islamic views on salvation and the eternity of Hell. It will be essential reading for scholars of Islamic intellectual history, theology, and comparative religion.
