Is it permissible for a daughter, who has been granted power of attorney by her mother, to use that power of attorney to withdraw her own and her sisters' money that the mother seized instead of paying the father's debts? And is the daughter considered an accomplice to the mother in sin for not distributing the inheritance justly?

If banks are usurious, then any money exceeding the principal capital is not permissible to benefit from and must be disbursed to the poor, the needy, and for public welfare. It is permissible for a daughter to take her share and her sisters' shares from their mother's money without her permission to save her from engaging in unlawful acts and to secure the rights of others. However, if banks are not usurious, then the profits are lawful and belong to the owners of the capital. Similarly, the debts of the deceased must be settled from their estate before it is divided among the heirs.
