Is it permissible for a daughter to prevent her mother from entering upon her (the daughter) while she is being washed (prepared for burial) after her death, knowing that the daughter suffered from the mother's ill-treatment and discrimination between her and her sister?

A daughter's disclosure to her mother of her desire to prevent her from entering upon her while she is being washed after her death is impermissible, as it contains harm to the mother. The mother's right to dutifulness remains and does not fall, no matter how much she has wronged. If the mother favors one of the children, she should be spoken to with courtesy and gentleness, or someone should mediate and speak to her, while being keen on showing her dutifulness and treating her kindly with good words and deeds. For, responding to evil with good brings affection and wards off the evil of Satan.
