The ruling on selling a dog and consuming its price

Question:
A questioner says: My colleague has rest houses and guard dogs, and he wants to get rid of one of them. What is the ruling on selling these animals, especially the dog, and on consuming the price?

Answer:
It is not permissible to sell a dog. The Prophet (peace and blessings be upon him) forbade the price of a dog, the fee of a fortune-teller, and the dowry of a prostitute, meaning a fornicator. Therefore, it is not permissible to sell dogs or cats, but it is permissible to sell animals that are beneficial in what Allah has made lawful.
