The ruling on endowing (waqf) for one son to the exclusion of the others and its relation to a bequest to an heir

The questioner:
He says: Honorable Shaykh, may Allah grant you success, is it permissible for a man to make an endowment (waqf) for one of his sons to the exclusion of the others? And is this like a bequest, which is not permissible for an heir?

The Shaykh:
Yes, the endowment (waqf) is permissible according to them; it is permissible for one of his sons or one of his heirs; because it is not a transfer of ownership, but rather a gift of benefit only, and what is prohibited is specifying some of the children with a transfer of ownership, and this is not a transfer of ownership,

The questioner:
We say: Honorable Shaykh, may Allah grant you success.

The Shaykh:
A bequest is not valid for an heir, unlike the endowment (waqf), which is valid for an heir; because it is not a transfer of ownership, but rather a permission of benefit only,
