Is the woman in the waiting period required not to leave the house?

The questioner : Now, regarding the woman in the waiting period, Shaykh, does the second question—may Allah reward you with good—mean that she is not allowed to go out of the house, or is it just for a certain period, like the waiting period?

The Shaykh : We are talking about the waiting period after a death.

The questioner : Yes, the waiting period of a woman whose husband has died, or of a divorced woman.

The Shaykh : A woman whose husband has died does not leave the house.

The questioner : She does not leave the house?

The Shaykh : Except for a need, such as an illness or something similar.
