Impermissibility of paying Sadaqah from the inheritance without the heirs' permission

Q 5: If a person dies, is it permissible to give, in Sadaqah (voluntary charity), to the poor from their money before dividing it among the inheritors and without taking their permission?

A: This is not permissible, because it is a kind of disposing of the money of others without their permission. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
