Cats and dogs are most commonly loved pets, and in this article, I will be discussing if they are allowed to keep, according to Hadith.
I am going to start with cats, since they are in fact permissible to keep, and there is nothing wrong with that because they are good and pure animals (not naajis, impure).
They also do not invalidate the prayer, and are said useful by the Prophet:
As for dogs, they are not permissible to keep, unless they are a watch or hunting dog. This is supported with Hadith:
This means that every day a person keeps a dog, his rewards and good deeds will get decreased, due to him having a dog.
Now you know the permissibility between these two animals. Cats can be kept freely, and dogs can only be kept as guard or hunting dogs.
May Allah bless you, and shukran.
