The remaining amount of the house's returns after offering the sacrifice devised in the will

Q: Attached is a copy of my grandmother's will, Hilah bint Al-Hamidy. Please advise me on what to do with the remaining amount of the revenue of her house after offering the Udhiyah (sacrificial animal offered by non-pilgrims) stipulated in her will, for the revenue has exceeded the cost of the Udhiyah. (Part No. 16; Page No. 381) Having perused the will, we find that it states the following: This is the bequest of Hilah bint Muhammad Al-Hamidy, in which she bequeathed the known house to Muhammad and his brothers. Whoever is in need among them may live in this house, and whoever is in no need of it should offer an Udhiyah. This will is witnessed by its clerk, `Abdul-`Aziz ibn Ahmad ibn `Abdullah in 1317 A.H.

A: If Muhammad or his brothers are in need of this house, they can live in it. However, if they are not, they should offer the Udhiyah. The remaining amount, after offering the Udhiyah, should be allocated for maintaining the house and for spending in charitable ways under the supervision of the trustee. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
