Shariah, the Islamic canonical law based on the teachings of the Koran, is a complex concept that has been interpreted in many ways over time and around the world. It plays a vital role in the lives of Muslims around the world, offering guidance on everything from personal morality to ritual practices, family life, and finance. But for many outside the Islamic world, Shariah is a misunderstood concept susceptible to media manipulation. In their new book, Shariah: What Everyone Needs to Know (Oxford University Press, 2018), Natana J. DeLong-Bas of Boston College and John Esposito of Georgetown University provide clear and even-handed answers to a wide range of questions, covering the history, development, content, and practice of Shariah. According to Publishers Weekly, “the clear writing and solid scholarship make [Shariah: What Everyone Needs to Know] a valuable reference work.” DeLong-Bas is an assistant professor of the practice in the Theology Department & Islamic Civilization and Societies program. She is also the author of Wahhabi Islam: From Revival and Reform to Global Jihad.
