Ibn Qayyim Al-Jawziy

Shams al-Dīn Abū ʿAbd Allāh Muḥammad ibn Abī Bakr ibn Ayyūb al-Zurʿī l-Dimashqī l-Ḥanbalī , commonly known as Ibn Qayyim al-Jawziyya or Ibn al-Qayyim for short, or reverentially as Imam Ibn al-Qayyim in Sunni tradition, was an important medieval Islamic jurisconsult, theologian, and spiritual writer. Belonging to the Hanbali school of orthodox Sunni jurisprudence, of which he is regarded as "one of the most important thinkers," Ibn al-Qayyim is today best remembered as the foremost disciple and student of the controversial fourteenth-century Sunni theologian Ibn Taymiyyah, with whom he was imprisoned in 1326 for dissenting against established tradition during Ibn Taymiyyah's famous incarceration in the Citadel of Damascus.
