In this collected volume, Aharon Layish demonstrates that legal documents are an essential source for legal and social history. Since the late nineteenth century, Islamic law has undergone tremendous transformations, some of which have strongly affected the basic features of its nature. The changes include the transformation of Islamic law from a jurists' law to a statutory law; the abolishment of waqf; the Islamization of tribal customary law; the creation of Sudanese legal methodologies strongly inspired by Sufi and Salafi traditions or Western law, and the emergence of an Israeli version of Islamic law.
