Bukhari :: Book 5 :: Volume 59 :: Hadith 338

Narrated Ibn Abbas:

Abu Talha, a companion of Allah's Apostle and one of those who fought at Badr together with Allah's Apostle told me that Allah's Apostle said. "Angels do not enter a house in which there is a dog or a picture" He meant the images of creatures that have souls.
