The ruling on each spouse washing the other after death

Question:
The honorable Abu Ibrahim also has another question regarding the ruling on each spouse washing the other. He says: In the etiquette of the Shaykh, what is the ruling?

Answer:
Yes, it is permissible for a husband to wash his wife if she dies, because 'Ali (may Allah be pleased with him) washed Fatimah, the daughter of the Messenger of Allah (peace and blessings be upon him). No one other than the husband is permitted to wash a woman, even if it is her father, her son, or any other relative of hers; rather, women wash her, except for the husband, who washes his wife. And the reverse is the same: a woman washes her husband, because Asma' bint Umayys (may Allah be pleased with her) washed Abu Bakr al-Siddiq (may Allah be pleased with him), and he was her husband. The Prophet (peace and blessings be upon him) said to A'ishah: "If I had died before you, I would have washed you." This is evidence that a husband washes his wife. As for anyone else, men are washed by men, and women do not wash them, even if it is his daughter, his sister, or his mother; she does not wash him. Rather, men wash him, except for the wife, who washes her husband. Yes.
