The ideology of the Islamic State, sometimes called Islamic Statism, has been described as being a hybrid of Salafism, Salafi jihadism, Sunni Islamist fundamentalism, Wahhabism, and Qutbism. Through its official statement of beliefs originally released by its first leader Abu Omar al-Baghdadi in 2007 and subsequently updated since June 2014, IS defined its creed as "a middle way between the extremist Kharijites and the lax Murji'ites".

Important doctrines of ISIL include its belief that it represents the restoration of the caliphate of early Islam, and that all Muslims are required to pledge allegiance to it; that a "defiled" Islam must be purged of apostasy, often with bloody sectarian killings, that the final Day of Judgment by God is near and will follow the defeat of the army of "Rome" by IS; that a strict adherence to following the precepts "established by the Prophet Muhammad and his earliest followers" is necessary, surpassing even that of other Salafi-Jihadi groups.

Importance

Experts disagree on the importance of ideology in IS. According to Cole Bunzel, not all members of IS are aware of the ideology of the group they support. On the other hand, Princeton scholar Bernard Haykel, who specializes in the study of IS, argues that many Western observers fail to understand the passionate attachment of IS—including to its rank and file—to religion doctrine: "Even the foot soldiers spout" Quranic verses "constantly. They mug for their cameras and repeat their basic doctrines in formulaic fashion, and they do it all the time." Fawaz A. Gerges also writes "researchers have tended to underestimate the power of the Salafi-jihadist ideology"—which he identifies as ISIL ideology—"at their own peril".

Names which are used to describe the group

The names which are used to describe the group or its ideology vary.

Ideology of the Islamic State

Sunni militant

USA Today writes that "The Islamic State is a group of Sunni militants" that "believes in the strict enforcement of Sharia law." In a conversation with a Western journalist (Thomas L. Friedman), a deputy crown prince of Saudi Arabia (Mohammad bin Salman Al Saud), described IS's message to Saudi and other Arab Muslims as: "The West is trying to enforce its agenda on you — and the Saudi government is helping them — and Iran is trying to colonize the Arab world. So we — ISIS — are defending Islam."

Qutbi

The Islamic State adheres to global jihadist principles and follows the hard-line ideology of al-Qaeda and many other modern-day jihadist groups. Sayyid Qutb is considered the "Father of the Jihadi-Salafi" movement, thus followers of the Salafi-Jihadi school are often derogatorily labelled as "Qutbi". Major elements of ISIL ideology as well as its extremist practices are thought to be derived from the Jihadist works of the Egyptian scholar Sayyid Qutb and the manuals of the hard-line wings of the Muslim Brotherhood movement.

The central role of Qutbist influence on Daesh is best captured in a saying popular among Islamic State supporters, attributed to Yemeni journalist Abdulelah Haider Shaye: “The Islamic State was drafted by Sayyid Qutb, taught by Abdullah Azzam, globalized by Osama bin Laden, transferred to reality by Abu Musab al-Zarqawi, and implemented by al-Baghdadis: Abu Omar and Abu Bakr.”

Wahhabi

Other sources trace the group's roots to Wahhabism. The New York Times wrote:
