If a husband loses his wife in death, does she become non mehram to him?
Is the husband not able to see her face for the last time before she is buried? Is she classed outside of Nikah?
Walaikumussalam w w
Nikah is for this worldly life. Death brings that to a close and severs all connections of this worldly life between husband and wife. So a husband cannot give ghusl to the wife nor can he look at her in a married way.
However, just looking at her face is allowed. Hazrat Mawlana Abdul Hayy lukhnawi ra has mentioned this in his fataawa.
The face being part of satar itself, is a mukhtalaf feeh mas’ala. (a disputed one) wallahu a’alam
