Does a woman leaving her home interrupt her waiting period?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: Regarding the waiting period of a woman whose husband has died, does her leaving her home interrupt her waiting period, such that she must restart the waiting period from the beginning?

Answer:
No, my brother. The waiting period is one thing, and the mourning period is another. Staying in the house is not part of the waiting period; it is part of the mourning period, which is one of the rulings of the waiting period. It is not permissible for her to go out except for a need. If she has a need, she goes out and returns, and that is permissible for her. Even if she does not observe the mourning period, her waiting period is valid, because the waiting period is one thing and the mourning period is another. If she does not observe the mourning period for the duration of the waiting period, the waiting period is completed even though she did not observe the mourning period, and her waiting period is valid.
