Is it permissible to hang curtains on the walls for decoration?

Question:
May Allah reward you, Honorable Shaykh. This questioner asks: Is it permissible to place curtains on the walls and on the doors for decoration?

Answer:
For decoration, no. But for necessity, there is nothing wrong with it. Aisha (may Allah be pleased with her) did this; she placed a curtain on the opening in the wall to cover it. When there is a need, there is nothing wrong with it. As for decoration, it is disliked. This is disliked because it is a form of extravagance and waste. Some of the Salaf disapproved of it, saying, "Do you make your houses like the Sacred Ka'bah, covering them?" This is waste and extravagance, so it should not be done.
