Washing and burying the deceased: What body parts of a woman is permissible to be seen by her young son, and is he allowed to wash her if she passes away?

No doubt the son is from the legal guardians, and she body parts can show in front of him which she cannot show to others. Thus, this is what is usually revealed from one’s arms, legs, hair and other than that which is permissible to show, as this is usually revealed to her child, father, brother and other than them from her guardians, except if she fears being put to trial by one of her guardians. Those who may look with desire should be prevented by her covering up just as she would from other than her guardians. As for the washing the body of the woman, then this is not performed by males except for the husband. Hence, it is not permissible for her son, father, or brother to wash her when she passes away, just as it is not permissible for her to wash any male except for her husband.
