Is it permissible to change the beneficiaries of a bequest if the amount exceeds the intended beneficiaries?

The questioner : The questioner says: I have a grandfather who passed away, and he had a house rented out for two riyals. He bequeathed it as a sacrifice. The value of this house was assessed, and the money grew until it is now close to one hundred and fifty thousand, consisting of shares in the electricity company, lands, and liquid funds. What is your opinion, O Shaykh? Is it possible to spend the bequest on the sacrifice and the remaining amount in various forms of charity? Or what should I do with it, especially since I am confused about what to do with it?

The Shaykh : But do you have the bequest with you now? Let us see it.

The questioner : The bequest is old, meaning it could be from the fourth or fifth grandfather.

The Shaykh : We must see it. After we see the document, we will inform you, if Allah wills. Then write me the wording of the question so that we can issue a ruling for you based on the question. Yes. Then.
