Answered by Ustadh Tabraze Azam
Is it permissible to use wallpaper with decorative and ornamental images of animals on it?
Usually, it would be best to avoid wallpaper that has depictions of animate life on it unless the wall will be covered by something else, such as bookshelves and the like, whereby the wallpaper won’t be visible. Such pictures are something that the Prophet (Allah bless him and give him peace) strongly interdicted.
However, if the pictures are very small, such that their details cannot be clearly seen, or they are silhouettes or mere outlines, the ruling would be otherwise as they don’t fit the definition of an interdicted picture. Nevertheless, it is still generally superior to avoid them as much as possible.
And Allah Most High knows best.
