Is it permissible to give one third of the deceased's property to charity on their behalf with the consent of the adult heirs?

Q 5: Someone passed away without making a will to take one-third out for charity. Is it permissible to give one-third of their property to charity on their behalf with the consent of the adult heirs?

A: It is permissible for the adult heirs to make a donation from their share of the inheritance or from their own property to charity on behalf of their deceased testator, as this would be doing a good deed for the deceased. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
