Do the rulings on Udhiyah apply to a sacrifice bequeathed after death, or does it fall under the rulings on bequests and must all of it be given as charity?

If a deceased person willed that a sacrifice (udhiyah) be offered on their behalf, the heirs are obligated to execute this will.

Scholars have differed regarding the ruling on eating from this sacrifice: - The Malikis and Hanbalis permitted eating from it and feeding others. - The Shafi'is (and this is the preferred view among the Hanafis) prohibited eating from it. They maintained that it is obligatory to give it away as charity, because the sacrifice was made on behalf of the deceased, and it is not permissible to eat from it except with their permission. If that is not possible, then it must be given as charity on their behalf.
