Can a woman who is observing ‘iddah following the death of her husband go out to pray Taraweeh and go to work?

My husband died 45 days ago, and I am used to going to pray Tarweeh in
the mosque the during the month of Ramadan. Isit permissible for me to
go to the mosque in orderto offer the prayer before my 'iddah is
complete? Is it permissible for me to do my job in the grocery store?
Please note that the grocery store is in the same house. Is it
permissible for the one who visits the graves to eat from any tree
that is planted in the graveyard?.
Praise be to Allaah.
Firstly:
We ask Allah to reward you in your calamity and to compensate you with
something better.
Secondly:
The woman who is observing 'iddah following the death of herhusband
should not go out at night except in cases of necessity. Your going
out to pray Taraweeh is not a necessity. Based on that, you should
pray Taraweeh in your house.
Thirdly:
It is permissible for the woman who is observing 'iddah following the
death of her husband to go out during the day to work, but when night
comes she has to stay at home. So there is nothing wrong with your
workingin the grocery, so long as that is during the day only.
Ibn Qudaamah (may Allahhave mercy on him) said in al-Mughni (8/130):
The woman who is observing 'iddah may go out for her needs during the
day, whether she is divorced or has recently lost her husband, because
of the report narrated by Jaabir who said: My maternal aunt was thrice
divorced, and she went out to harvest her palm trees. She was met by a
man who rebuked her and toldher not to do that. She mentioned that to
the Prophet (blessings and peace of Allah be upon him) and he said:
"Go out and harvest your palm trees, for perhaps you willgive charity
from it or do something good." Narrated by al-Nasaa'i and Abu Dawood.
Mujaahid narrated: Some men were martyred on the day of Uhud and their
wives came to the Messenger of Allah (blessings and peace of Allah be
upon him) and said: O Messenger of Allah,we feel lonely at night; can
we sleep in the house of one of us and then in the morning we will go
back to our own houses? The Messenger of Allah (blessings and peace of
Allah be upon him) said: "(Stay together and) talk in the house of one
of you, then when you want to sleep, let each one of you go to her own
house." So she is not allowed to stay overnight anywhere but in her
own house, and should not go out at night, except in case of
necessity, because the night is the time when immorality is most
likely to occur, unlike the day, which is the time when most people go
about their needs and earn a living, and buy what they need. End
quote.
It says in Fataawa al-Lajnah al-Daa'imah (20/440): The basic principle
is that a woman should observe mourning in the house of her husband in
which she waswhen he died, and she should not go out of it except in
case of need or necessity, such as going tothe hospital if she is
sick, or buying what she needsfrom the marketplace such as bread and
the like,if she does not have any one with her who can do that. End
quote.
As for eating from the trees that are planted in the graveyard, there
is nothing wrong with that, but you should note that the Prophet
(blessings and peace of Allah be upon him) forbade women to visit the
graves. This has been discussed in the answer toquestion number 8198 .
And Allaah knows best.
