The ruling on a woman in the waiting period taking a bath for cleanliness and cooling off

Question:
Is it permissible for a woman in the waiting period to take a bath during the mourning period for the sake of cleanliness and cooling off, and not for the sake of menstruation or post-natal bleeding?

Answer:
As you heard, it is permissible for her to take a bath, clean herself, cool off, and use non-restricted cleaning agents; there is no obstacle. However, some of the common people, and some women in particular, legislate rulings for the deceased. They say she must not go up to the roof, must not look at the moon, and must not speak to people; if they greet her, she must not respond. All of this is from lying and ignorance. This speech is not permissible. It is not permissible for anyone to speak about the rulings of the Shari'ah without knowledge. This is not permissible, they say. She must not go out to the yard, must not climb the stairs, and must not see the moon. So, glory be to Allah! They have taught us to lie about Allah, Glorified and Exalted is He.
