The audio describes Al Azif, a legendary book of black magic from the 8th century. This text supposedly holds secrets predating humanity and instructions for communicating with otherworldly beings. Efforts to destroy it have failed, as it mysteriously reappears. In the 19th century, a poet, Hassan al-Mansour, studied the book and performed a ritual from it. Following the ritual, Hassan vanished, leaving behind a journal speaking of imprisonment by the Jin described in the book. The book is portrayed not just as a guide but as a prison for those who seek its knowledge.
