What is the ruling on one who sells land that belongs to his mother so that she can perform Hajj with the proceeds?

Question:
I have a piece of land in the Jizan region, and I have an older brother who says that this land is under protection, and its produce is given in charity, that it is an endowment (waqf) for Allah the Exalted. Is there protection in this land and is its produce given in charity? It is tilled and its produce is given in charity on the basis that it is an endowment for Allah the Exalted. However, after his death, it became clear to me that the land is among my mother’s properties. Is it valid for me to sell it and give my mother a ticket to the Holy House from the proceeds of the aforementioned land?

Answer:
This matter is referred to the court, may Allah bless you. Present the documents you have with your opponents and your brother’s heirs so that the case can be examined. This is a matter for the court, not for a fatwa here. Yes.
