Ibn Qudāmah al-Maqdisī Muwaffaq al-Dīn Abū Muḥammad ʿAbd Allāh b. Aḥmad b. Muḥammad (Arabic: ابن قدامة المقدسي موفق الدين ابو محمد عبد الله بن احمد بن محمد ; 1147 - 7 July 1223), often referred to as Ibn Qudamah for short, was a Sunni Muslim ascetic, jurisconsult, Traditionalist theologian. Having authored many important treatises on Islamic jurisprudence and religious doctrine, including one of the standard works of Hanbali law, the revered al-Mug̲h̲nī, Ibn Qudamah is highly regarded in Sunnism for being one of the most notable and influential thinkers of the Hanbali school of orthodox Sunni jurisprudence. Within that school, he is one of the few thinkers to be given the honorific epithet of Shaykh of Islam, which is a prestigious title bestowed by Sunnis on some of the most important thinkers of their tradition. A proponent of the classical Sunni position of the "differences between the scholars being a mercy," Ibn Qudamah is famous for having said: "The consensus of the Imams of jurisprudence is an overwhelming proof and their disagreement is a vast mercy."
