Qasim bin Abdur Rahman narrates that a man, during his terminal illness, sought permission from his heirs to bequeath more than one-third of his wealth. They granted him permission, but when the man died, they retracted their consent. Hazrat Ibn Mas'ud (may Allah be pleased with him) was asked about this matter, and he said: They have the right to do so, and it is not permissible to compel them against it.
