Impermissibility of spending Waqf money or its profits dedicated to a Masjid on a graveyard

Q 1: We have a farm that was given as a Waqf (endowment) to the Masjid (mosque) in our village. Next to that farm is another farm, owned by one of the residents who donated it for use as a cemetery. Is it permissible to join the Waqf farm to this cemetery?

A: It is obligatory for the Waqf to remain as it is, and its income given wherever the donor specified for it to go. If the benefit ends or it can no longer be used in the way specified by the Waqf donor, it is obligatory to refer the matter to the judge to resolve the issue. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
