Abu Talha reported the Prophet as saying, “The angels do not enter a house which contains a dog or pictures.” (Bukhari and Muslim.)
Exposition of the Hadith on Dogs and Images
This noble hadith from Sahih al-Bukhari and Sahih Muslim, also recorded in Mishkat al-Masabih 4489, addresses the spiritual consequences of keeping dogs and images within one's dwelling. The angels, beings of light and purity charged with recording deeds and bringing divine mercy, refrain from entering such homes.
Scholarly Commentary on the Prohibition
The prohibition specifically concerns keeping dogs without legitimate need, as established in other authentic narrations. Permissible necessities include hunting, guarding livestock, or protecting crops. The wisdom behind this ruling preserves the household's spiritual purity and maintains the angels' continuous presence.
Regarding images (suwar), the prohibition encompasses anything with a soul that is depicted in a manner claiming to rival Allah's creation. This includes statues and detailed drawings or photographs of animate beings. The scholars differentiate between these and forms of images that are incomplete or lack detail, which carry lesser restrictions.
Practical Implications and Exceptions
This hadith does not imply dogs are inherently impure in all circumstances, but rather highlights the spiritual consequence of housing them unnecessarily. For necessary purposes, dogs may be kept in designated outdoor areas.
Concerning images, exceptions exist for educational materials, children's toys, and necessary identification documents where the image serves a functional purpose without reverence or display. The core principle is avoiding what may lead to shirk or distract from Allah's remembrance.
