شمس الدين محمد بن أبي بكر بن أيوب ،ابن القيم الجوزية ابن القيم‎
The closest companion and a student of Ibn Taymiyah who shared with him the moments of ease and hardship, until the latter’s death in the citadel. His works in various Islamic sciences earned him much acceptance and fame. Some of his important works include Zaad al-Ma’ad in Seerah and Fiqh, I’lam al-Muwaqqi’in in Usul al-Fiqh, and al-Kafiyah fil-Intisar lil-Firqat al-Najiyah, an ode rhyming in the letter Nun on Hanbali theology, which is taught and studied in Hanbali schools until today.
Ibn al-Qayyim was fervent in his devotion to his teacher, and he was an excellent student and disciple of the great Muslim scholar Imam Taqiyyu-Deen Ahmad Ibn Taimiyyah. He defended his religious opinions and approaches, and he compiled and edited most of his works, and taught the same.
Because of their perception and opinions, both the teacher and the student were unjustly persecuted, tortured, and humiliated in public by the local authorities then, and they were imprisoned in a single cell, while other disciples were kept separate in the central prison of Damascus, still known to-date as al-Qal‘a. Among the imprisoned scholars, there also was a young man named Ibn Kathïr who later on became as the most renowned Muslim scholar and compiler of the most comprehensive Qur’anic commentaries ‘Tafsïr Ibn Kathïr.’
Upon the death of Imam Ibn Taimiyyah, the disciples were set free from prison, and Imam Ibn al-Qayyim al-Jawziyya furthered his studies, and held study circles and classes for his own students. Ibn Jawziyya taught Islamic Jurisprudence at al-Sadriyya school, in Damascus, before he held the position of the Imam of the Jawziyya school for a long period. Most of his writings were compilations, although he authored several books himself, and manuscripts with his own handwriting are preserved today in the central Library of Damascus.
