The Messenger of Allah said: "The angels do not enter any house in which there is an image." Busr said: "Then Zaid fell sick and we went to visit him, and on his door there was a curtain on which there was an image. I said to 'Ubaidullah Al-Khawlani: 'Didn't Zaid tell us about images yesterday?' 'Ubaidullah said: 'Didn't you hear him say: Except for patterns on fabrics?'"
