This work investigates the historical and legal continuity between the laws for non-Israelites in the Hebrew Bible and the development of Qur'anic law. Holger M. Zellentin, a scholar specializing in the intersection of late antique religious traditions, utilizes a comparative legal framework to trace how specific legislative concepts evolved across the Hebrew Bible, the New Testament, and early Christian traditions before influencing nascent Islam. The author argues that the legal status of the 'Gentile' serves as a critical bridge in understanding the formation of Islamic jurisprudence.
