One can bathe his or her dead spouse and this is the doing of  the companions, may Allah be pleased with them.

What these ignorants are saying is not true.

Sheikh,I would like to know if Hazrat Ali gave bath to Fatimah binte Mohammed Sallalahu Alaihe wasallam after her death. Reason for this question is because here in my city in India Marriage is considered to be dissolved after the death of anyone of the partner & they become non mehram.Hence it is not allowed to see each other after the death.
