Manager or custodian of waqf (charitable endowment). The mutawalli is chosen by the founder of the waqf and is responsible for the administration of waqf property in the best interest of beneficiaries. The mutawalli's first duty is preservation of property, then maximization of revenues for beneficiaries. The waqf document usually mentions how the mutawalli is to be compensated for this work, but if the document does not specify it, the mutawalli either works on a volunteer basis or seeks assignment of compensation by the court, which is the authority of reference with regard to all matters and disputes related to waqf. The mutawalli is often a member of the founder's family, typically a descendant, enabling the family to maintain some benefit from the waqf.
