Praise be to Allaah.
The woman in mourning whose husband has died has to stay in
her house and not go out, because the Messenger (blessings and peace of
Allaah be upon him) said to the woman whose husband had died: “Stay in your
house until the term prescribed is fulfilled (cf. al-Baqarah 2:234).” So the
woman who is in mourning should stay in her house and should not wear
beautiful clothes, put on perfume, apply kohl, or wear jewellery. There are
five things which the woman in mourning must observe:
Staying at home until her
Not wearing beautiful clothes;
rather she may wear clothes that are not beautiful, such as black, green, or
blue -- so long as they are not beautiful.
She should not wear jewellery
of gold, silver, diamonds, pearls and so on. A watch is a kind of jewellery,
because it is worn for beauty and adornment.
Not wearing kohl; which
includes putting any kind of adornment on her face that women are accustomed
to doing nowadays, apart from water and soap and the like.
Not wearing perfume; she should
avoid all kinds of perfume except when purifying herself following menses.
She may go out for necessary purposes, such as going to court or to the hospital or to the marketplace. End quote.
