An insightful account of one man’s drastic evolution from religious fervor to enlightened peace.

Maajid Nawaz spent his teenage years listening to American hip-hop and learning about the radical Islamist movement spreading throughout Europe and Asia in the 1980s and ’90s. At sixteen, he was already a ranking member in Hizb ut-Tahrir, a London-based Islamist group. He quickly rose through the ranks to become a top recruiter, a charismatic spokesman for the cause of uniting Islam’s political power across the world. Nawaz was setting up satellite groups in Pakistan, Denmark, and Egypt when he was rounded up in the aftermath of 9/11 along with many other radical Muslims.

He was sent to an Egyptian prison where he was, fortuitously, jailed along with the assassins of Egyptian president Anwar Sadat. Twenty years in prison had changed the assassins’ views on Islam and violence; Maajid went into prison preaching to them about the Islamist cause, but the lessons ended up going the other way. He came out of prison four years later completely changed, convinced that his entire belief system had been wrong and determined to do something about it.

He met with activists and heads of state, built a network, and started a foundation, Quilliam, to combat the rising Islamist tide in Europe and elsewhere, using his intimate knowledge of recruitment tactics in order to reverse extremism and persuade Muslims that the “narrative” used to recruit them—that the West is evil and the cause of all Muslim suffering—is false. Radical is a fascinating and important look into one man’s journey out of extremism and into something else entirely.
