The ruling on covering walls with curtains

What is the ruling on a person who covers the walls of his sitting room with curtains that cover the four walls of the room, knowing that it has only one window?
Answer: It is better and more preferable to leave the walls uncovered; based on the hadith , but there is no harm in it; it is not forbidden, because we are not aware of any prohibition against it. Rather, it is permissible, though leaving it uncovered is better. So there is no blame in doing so if he does it for adornment, or to keep out dust, or for other reasons. There is no blame in that, if Allah wills, but leaving it uncovered is better. Yes.
The presenter: May Allah reward you.
