In case of death of a person, it is practiced by some group of Muslims who follow Hanafi madhab in India that the society forbids-do not allow the wife of the person to see her own husbands dead body. They claim that when a person dies, his wife becomes a widow and she should not be allowed to go infront of any(mahram) man who is dead or alive. It is assumed by them that her husband’s dead body becomes haram to see. Is there any authentic hadith that confirms this? Please explain.

Praise
be to Allaah.

This question involves two issues: 

1 – A woman seeing her husband’s body after his death

2 – A woman seeing her mahrams. 

1 – It is permissible for a woman to see her husband’s
body, and there is no reason why she should not. Indeed, a wife has
the right to wash her dead husband. Imaam Maalik narrated in al-Muwatta’
from ‘Abd-Allaah ibn Abi Bakr that Asmaa’ bint ‘Umays washed Abu Bakr
al-Siddeeq when he died, then she went out and asked the Muhaajireen
who were present, “I am fasting and the day is very cold; do I have
to do ghusl?” and they said, “No.” (al-Janaa’iz, 466). The author
of al-Muntaqa ‘ala Sharh al-Muwatta’ said concerning this hadeeth:
this indicates that it is permissible for a woman to wash her husband
after he has died, because this happened in the presence of a number
of the Sahaabah, especially since Abu Bakr had left instructions in
his will to that effect. No difference of opinion is known of among
the Sahaabah concerning this matter, which indicates that there was
consensus. 

It was narrated that ‘Aa’ishah said, “If I could go back
and change anything, nobody would have washed the Messenger of Allaah

(peace and blessings of Allaah be upon him) except his wives. ” (narrated
by Ibn Maajah, al-Janaa’iz, 1453; classed as saheeh by al-Albaani
in Saheeh Ibn Maajah, no. 1196). If a woman is permitted to
wash her husband;s body, then it is definitely permitted  for her
to see her husband’s body. 

This ruling applies only if the woman is still within
the ‘iddah period. If her ‘iddah period has ended, for example if she
was pregnant but gave birth straight after her husband died, then it
is not permissible for her to wash him or to see him. 

I (Shaykh al-Munajjid) asked Shaykh Ibn ‘Uthaymeen (may
Allaah have mercy on him) before he died about a man who dies and his
wife gives birth a few hours later – can she wash her husband? 

He replied: No, because
when she gives birth the connection between her and her husband is severed,
so it is not permissible for her to wash him, because he is now no longer
her husband. 

Mi’ah Faa’idah min al-‘Allaamah al-Shaykh Ibn ‘Uthaymeen
(tape). 

What is forbidden is for women to wail over the deceased.
It was narrated in a hadeeth that Umm ‘Atiyah (may Allaah be pleased
with her) said: “The Prophet

(peace and blessings of Allaah be upon him) took our pledge of allegiance
to him on the grounds that we would not wail (over the dead). None of
us fulfilled their promise except five women: Umm Sulaym, Umm al-‘Alaa’,
the daughter of Abu Sabrah the wife of Mu’aadh and two other women,
or the daughter of Abu Sabrah, the wife of Mu’aadh and one other woman.”
(Narrated by al-Bukhaari (al-Janaa’iz, 1223). 

It was narrated from Abu Maalik al-Ash’ari that the Prophet

(peace and blessings of Allaah be upon him) said: “There are four things
in my ummah from the jaahiliyyah which they will not give up: pride
in one’s ancestry, slandering the lineage of others, seeking rain from
the stars and wailing over the dead. If the woman who wails does not
repent before she dies, she will be raised on the Day of Resurrection
wearing a garment of tar and a shirt of scabs.’ (Narrated by Muslim,
al-Janaa’iz, 1550). 

2 – It is permissible for a woman to see her mahrams,
and she does not have to observe hijaab in front of them. 

There is no connection
between the death of a woman’s husband and her seeing her mahrams. Hence
it is recommended for her mahrams to offer condolences to her, by them
seeing her, shaking hands with her, sitting with her and talking to
her. No dispute is known among the scholars concerning this. 

Al-Nawawi (may Allaah
have mercy on him) said: al-Shaafa’i and his companions said: it is
recommended for all the relatives of the deceased to offer condolences
to his wife, old and young, men and women, unless the wife is young,
in which case only her mahrams should offer condolences. 

(al-Majmoo’, 5/277). 

What the questioner describes is nothing more than the
myths and ignorance of the common people. 

Shaykh Muhammad ibn Ibraaheem (may Allaah have mercy
on him) was asked about a woman covering her face in front of her mahrams.
He said: 

That is not permissible, because it is not part of Islam,
rather that is the myths and ignorance of the common people.
