Have you ever thought of something you do on a regular basis that could be from the shaytan (devil)? Have you ever done something and thought twice about it? Or do you do something unintentionally that could be a whaswasa from shaytan? Well then, I recommend you read this book. It teaches you things that you may not notice in yourself. Waswasah, the whispering of Shaytan is a book written by Imam ibn Qayyim al-Juzziyah. It is a clear book that is very easy to understand. It is organized into different headings allowing you to find any point you need fast. It has interesting facts with references from the Noble Quran, from authentic Hadith Narrators (RA) as well as Hadith Books (Sahih Muslim and Sahih Bukhari, etc.).
