Islamic Enlightenment in a Radical Age opens a window to trends of innovation and openness in modern Islam in the mid-twentieth century, a period marked by decolonization, the rise of centralized regimes, and the emergence of Jihad organizations. Important agents in the development of the reformist discourse were Mustafa al-Saba'i and the "Muslim Brotherhood" in Syria from 1946 to 1964. Under al-Saba'i's leadership, the Muslim Brotherhood strove to establish an Islamic Enlightenment that sought to elevate the stature of believers and integrate them into the wider world, while preserving their indigenous identity. Al-Saba'i's rich intellectual and public work has been neglected in the scholarly literature, and this book brings him to the forefront and does him historical and historiographical justice. Al-Saba'i called for the revival of the heritage of Islam and its connection to universal values of freedom and justice, humanism and brotherhood, democracy and nationalism. He served as a voice for the voiceless in society through a commitment to public education, social legislation, and support for women's rights, subject to moral reservations. By promoting a dynamic version of Islam—attentive and responsive to key issues on the public agenda—Al-Saba'i and his movement contributed to preserving the diversity of Islamic thought in an era of puritanism, radicalization, and violence.
