To whom does ownership transfer in a dedicated endowment (Waqf)?

Primary text

In the apparent view of the Madhhab (school of thought), ownership transfers to the beneficiaries of the endowment. Imam Ahmad stated that if a house is endowed upon the children of his brother, it becomes their possession. This indicates that they own it. The basis for this is that the endowment is a cause that removes the ownership of the endower, and the result is directed toward someone eligible to possess it in a manner where the asset does not leave its monetary essence, thus ownership must transfer to them, similar to a gift or a sale. Furthermore, if it were merely the possession of usufruct, it would not be binding like a temporary loan (ariya) or tenancy, nor would the owner's right be removed like in a loan, and it differs from manumission (itq) where the asset is removed from monetary value. The inability to dispose of the principal does not prevent ownership, as seen with the mother of the child (umm walad).
