This audiobook emphasizes the importance of observing the ritual requirements of Islam, the actions that would lead to salvation, and avoidance of sin. The factor that set the Kimiya-yi sa'adat apart from other theological works at the time was its mystical emphasis on self-discipline and asceticism.
The Author, Al Ghazali, is considered the greatest spiritual and legal philosopher in Islamic history. Beside his work that successfully changed the course of Islamic philosophy - the early Islamic neoplatonism developed on the grounds of Hellenistic philosophy, for example, was so successfully refuted by Ghazali that it never recovered - he also brought the orthodox Islam of his time in close contact with Sufism.
Please note: This audiobook is in Arabic.
