Al-Wabil as-Sayyib

الوابل الصيب من الكلم الطيب

A work on the virtues of dhikr (remembrance of Allah) and its transformative effects on the heart and soul. Ibn al-Qayyim enumerates over seventy benefits of consistent dhikr, discusses the types of remembrance prescribed in the Sunnah, and describes how dhikr protects against spiritual diseases. The book is both a practical guide and a motivational text that has inspired Muslims for centuries.
