Is it permissible for the heirs to take their share of the money left by the deceased, or does it belong solely to his daughter, knowing that he gifted his house to his brother and second wife fearing that his divorced wife and daughter would inherit from it?

The money left by the deceased is an inheritance to be divided among all his heirs; it is not exclusive to his daughter. The deceased's division of his house between his brother and his wife while he was on his deathbed is considered a will, and a will made in favor of an heir is not valid unless the rest of the heirs approve it, due to the saying of the Prophet, peace and blessings be upon him: "Indeed, Allah has given every rightful person his right, so there is no will for an heir."
