Dedicating two Ud-hiyahs as Waqf, one for herself and her father, the other for her husband and his parents, and wishing to dedicate a third for her r

Q: I would like to inform you that I have given the house which is located at Plot no. 222 in the plan of Marrat as Waqf. This house is mine according to the title issued from Marrat Municipality under no. 143 on 9/11/1401 A.H.I have devoted the building's revenue for the purchase of two sacrificial animals; one for my father and myself and the second for my husband and his father according to the title issued from the court of Marat no. 127 on 27/12/1411 A.H. My son died after I had given the house for Waqf (endowment) and did not leave behind money or property as he was still a student in college. I would like to assign (Part No. 16; Page No. 106) a third sacrifice from the revenue of this house. Could you kindly advise me.

A: It is not permissible to add a third sacrifice to the previous two because the house is assigned only with the previous two sacrifices and for acts of goodness. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
