What is the ruling on hanging a Persian rug in the house that has pictures of humans and animals on it, when the husband refuses to remove it?

Hanging carpets devoid of images of living beings is considered makrooh (disliked) by scholars, unless it involves extravagance or wastefulness.

As for carpets that contain images, their ruling varies depending on the type of image: 1. Three-dimensional (sculptural) images: These are forbidden by scholarly consensus. 2. Complete images of living beings: There are three opinions regarding these: First opinion: They are not forbidden. Second opinion (Maliki school and some early Muslims): They are not forbidden unless they are three-dimensional, complete in their limbs, and made of durable materials. Third opinion (Hanafi, Shafi'i, and Hanbali schools): Depicting living beings is absolutely forbidden, whether they cast a shadow or not. 3. Incomplete images of living beings: These are permissible if a vital organ is missing. 4. Images of non-living beings (such as trees and buildings): These are permissible according to the majority of scholars. 5. Fictional images of living beings: Their ruling is the same as that of real living beings.

Based on this, if the husband adopts the Maliki opinion that flat, non-three-dimensional images are permissible, then there is no harm in not removing them. However, it is preferable and more cautious to use or treat them as floor coverings and the like.
