“Once Gabriel promised the Prophet (that he would visit him, but Gabriel did not come) and later on he said, ‘We, angels, do not enter a house which contains a picture or a dog.’” — Sahih Bukhari 4.54.50
“Abdullah (b. Umar) (Allah be pleased with them) reported: Allah’s Messenger (may peace be upon him) ordered the killing of dogs and we would send (men) in Medina and its corners and we did not spare any dog that we did not kill, so much so that we killed the dog that accompanied the wet she-camel belonging to the people of the desert.” — Sahih Muslim 10.3811
“Narrated ‘Aisha: The things which annul the prayers were mentioned before me. They said, “Prayer is annulled by a dog, a donkey and a woman (if they pass in front of the praying people).” I said, ‘You have made us (i.e. women) dogs.’ I saw the Prophet praying while I used to lie in my bed between him and the Qibla. Whenever I was in need of something, I would slip away. for I disliked to face him.” — Sahih Bukhari 1.9.490
But remember, Sharia is benign and completely compatible with Western society.
A newly-wed man who was arrested in a Western suburb of Mashhad (Northeast Iran) for walking his pet dog in public was sentenced to six months in prison for violating Iran’s anti-pet laws.
But an Appeals court suspended the prison term for two years subject to probation and parole. Anti pet-ownership laws in urban areas of Iran are said to be rooted in religious edicts, health concerns and (Anti-Westernization) cultural norms.
