Praise be to Allaah.
We put the following question to Shaykh Muhammad Saalih ibn Uthaymeen:
Her husband has bought a house with haraam money. Can she refuse to live in it?
He replied, may Allaah preserve him:
Praise be to Allaah. No, she cannot refuse to live in it, because she is living there rightfully. It is he who has acquired the house in a wrongful manner. But if he has seized another person's house by force, then she has the right to refuse to live in it.
And Allaah knows best.
