Is acceptance (Qabul) required for the validity of a perpetual endowment (Waqf) concerning the beneficiary?

Primary text

If the endowment is designated for a non-specific recipient, such as the poor (al-masakin) or structures like mosques and bridges (al-qanatir), it is not required to have acceptance. The opinion supporting the non-requirement of acceptance argues that Waqf is a type of property divestment that prohibits sale, gift, or inheritance, thus not necessitating acceptance, analogous to manumission (i'taq). Furthermore, Waqf does not exclusively benefit a specific individual but establishes a right for future generations consecutively, making it similar to an endowment for the poor, which is not invalidated by one beneficiary's rejection, nor does it depend on their acceptance. This view is the established position of Al-Shafi'i.
