Waqf is an Islamic charitable endowment where a Muslim dedicates assets for religious or charitable purposes in perpetuity. A waqf is established through a legal contract where a waqif, or donor, transfers ownership of an asset to a mutawalli, or trustee, to administer it. The income generated is used for purposes outlined by the waqif, such as maintaining a mosque, supporting the poor, or funding an educational institution. The Mussalman Wakf Validating Act of 1913 defines waqf under Indian law and establishes rules regarding its creation, registration, and administration to benefit religious and charitable causes in accordance with Islamic principles.
