Waqf

A waqf, also called a ḥabs, or mortmain property, is an inalienable charitable endowment under Islamic law. It typically involves donating a building, plot of land or other assets for Muslim religious or charitable purposes with no intention of reclaiming the assets. A charitable trust may hold the donated assets. The person making such dedication is known as a waqif ('donor') who uses a mutawalli ('trustee') to manage the property in exchange for a share of the revenues it generates. A waqf allows the state to provide social services in accordance with Islamic law while contributing to the preservation of cultural and historical sites. Although the waqf system depended on several hadiths and presented elements similar to practices from pre-Islamic cultures, it seems that the specific full-fledged Islamic legal form of endowment called waqf dates from the 9th century AD.
