This intellectual biography of Muhammad al-Shawkani, one of the founding fathers of modern Islamic reformism, is also a study of an important transitional period in Yemeni history which saw the shift from traditional Shi'ism to Sunni reformism. The transition propelled political, religious and social change. While Shawkani espoused a socio-religious order which echoed aspects of Western thinking, the book demonstrates that it was indigenous to Islamic thought. Shawkani's ideas remain vital to the intellectual debates happening in Islam today.
