Denying the holiness of the Koran or the prophecies of Muhammad is straightforward apostasy. But Zarqawi and the state he spawned take the position that many other acts can remove a Muslim from Islam. These include, in certain cases, selling alcohol or drugs, wearing Western clothes or shaving one’s beard, voting in an election—even for a Muslim candidate—and being lax about calling other people apostates. Being a Shiite, as most Iraqi Arabs are, meets the standard as well, because the Islamic State regards Shiism as innovation, and to innovate on the Koran is to deny its initial perfection. (The Islamic State claims that common Shiite practices, such as worship at the graves of imams and public self-flagellation, have no basis in the Koran or in the example of the Prophet.) That means roughly 200 million Shia are marked for death. So too are the heads of state of every Muslim country, who have elevated man-made law above Sharia by running for office or enforcing laws not made by God.
Following takfiri doctrine, the Islamic State is committed to purifying the world by killing vast numbers of people. The lack of objective reporting from its territory makes the true extent of the slaughter unknowable, but social-media posts from the region suggest that individual executions happen more or less continually, and mass executions every few weeks. Muslim “apostates” are the most common victims. Exempted from automatic execution, it appears, are Christians who do not resist their new government. Baghdadi permits them to live, as long as they pay a special tax, known as the jizya, and acknowledge their subjugation. The Koranic authority for this practice is not in dispute.Graeme Wood
Complementing the report on how ISIS started, this long and well-researched article goes the other way, searching for ISIS’ ultimate goals and fate. Short answer: to bring about the End of Days in a final battle with the armies of Rome.
Properly contained, the Islamic State is likely to be its own undoing. No country is its ally, and its ideology ensures that this will remain the case. The land it controls, while expansive, is mostly uninhabited and poor. As it stagnates or slowly shrinks, its claim that it is the engine of God’s will and the agent of apocalypse will weaken, and fewer believers will arrive. And as more reports of misery within it leak out, radical Islamist movements elsewhere will be discredited: No one has tried harder to implement strict Sharia by violence. This is what it looks like.
