Muhammad Tahir ul-Qadri, one of the leading practitioners of Sufism, an Islamic sect that focuses on peace and tolerance, has issued a 600-page fatwa denouncing terrorism and suicide bombings. The Pakistani-born scholar said terrorists are destined for hell—not heaven, as they usually believe—and that he was moved to action because of the radicalization of Muslims at British universities. The Quilliam Foundation, an anti-terrorism think-tank, called the judgment “the most comprehensive theological refutation of Islamist terrorism to date.”
