There is no harm in the Husband washing his wife
Question:
Verily, we have often heard from the common people that the wife is forbidden to her husband after death, meaning after her death. They say that it is not permissible for him to look at her nor is he allowed to put her into her place in the grave. Is this correct? Please answer us, and may Allah bless you.
Answer:
The legislative proofs of Islam prove that there is no harm in the woman washing her husband (after death) and looking at him, and there is no harm in the husband washing his wife and looking at her. Asma' bint Umays washed her husband Abu Bakr As-Siddiq, and Fatimah willed that 'Ali (her husband) wash her (upon her death) (may Allah be pleased with them). And Allah is the Giver of success.
