Regarding the ruling of washing a dead body; can a man or woman wash the body of their spouse? In my East Asian culture the scholars say that the nikah is ended when one of the spouse dies, and therefore it's haraam to wash their body. I tried on islamqa, but their not giving a definite answer.
The Saudi scholar Ibn Baaz says there is nothing wrong with washing a spouse’s body. He mentions that Asmaa’ bin Umais (the wife of Abu Bakr, may Allah be pleased with him and her) washed Abu Bakr’s body when he died, and that Fatima (daughter of the Prophet, and his family) washed Ali’s body.
