Ahmad ibn Umar al-Hazimi (Arabic: أحمد بن عمر الحازمي, romanized: Aḥmad ibn ʿUmar al-Ḥāzimī) is a Saudi scholar whose interpretation of takfir (excommunication) gave rise to the eponymous Hazimi branch of Wahhabism. A relatively unknown figure until he publicised his teachings in Tunisia after the 2011 revolution, some followers of al-Hazimi's views briefly wielded considerable power within the Islamic State of Iraq and the Levant (ISIS). He was arrested and imprisoned by Saudi authorities in 2015 due to his extremist ideology.
