Ad-Dā’ wa Ad-Dawā’ (al-Jawab al-Kaafi) - (Imam ibn al-Qayyim)

This seminal Islamic text by Imam Ibn Qayyim Al-Jawziyyah, published by Dar Ibn Hazm in Arabic, serves as a comprehensive guide to diagnosing and treating spiritual maladies. Drawing from the Qur'an and Sunnah, the work examines various spiritual diseases—including sin, worldly desires, and doubt—and prescribes remedies rooted in faith, such as sincere repentance, Allah-consciousness, and righteous conduct. It remains essential reading for those pursuing spiritual reformation and deeper Islamic understanding.
