A woman whose husband abandoned her for twenty years, then he died: does she have to observe the waiting period?

Question:
May Allah reward you. One of the sisters says: Please give us a ruling, and may you be rewarded. A woman’s husband died, and he had been abandoning her for twenty years. He did not come to her, and he did not provide for her, even though he was living in the same neighborhood as she was. He did not divorce her, but he was married to another woman. Does the waiting period for a widow apply to her?

Answer:
Yes. As long as she remains in his marriage bond, she is required to observe what is required of a widow: the waiting period for death and the mourning period for him. She is entitled to her inheritance from him; she is entitled to her inheritance from him because she is still his wife. Yes.
