Abu Omar al-Baghdadi was the first leader of Ideology of the Islamic State of Iraq and the Levant or ISIS, a radical Islamist who condemns followers of secular law as disbelievers and Bernard Haykel described al-Baghdad's creed as untamed Wahhabism.
Bernard Haykel has described ISIL leader Abu Bakr al-Baghdadi's creed as "a kind of untamed Wahhabism". Through the official statement of beliefs originally released by its first leader Abu Omar al-Baghdadi in 2007 and subsequently updated since June 2014, ISIL defined its own creed as "a middle way between the extremist Kharijites and the lax Murji'ites". The Islamic State of Iraq and the Levant (ISIL; /asl, asl/), also known as the Islamic State of Iraq and Syria (ISIS; /ass/), officially known as the Islamic State (IS) and also known by its Arabic acronym Daesh (, Daish, IPA: [da), is a militant Islamist group and a former unrecognised proto-state that follows a fundamentalist, Salafi jihadist doctrine of Sunni Islam. Following Salafi-Wahhabi tradition, ISIL condemns the followers of secular law as disbelievers, putting the current Saudi Arabian government in that category. ISIL's ideology represents radical Salafi Islam, a strict, puritanical form of Sunni Islam.
