The Ruling on Keeping Dogs For Other Than Hunting, and the Ruling on Their Prey When They Hunt

Question :

I have dogs that I breed, and they are not of the well hunt) permissible or forbidden? And what is the ruling on breeding such animals as these? It is not permissible for a person to keep a dog unless it is a hunting dog, a farming dog, or a sheepdog, as confirmed by the narration from the Prophet ﷺ As for these dogs indicated by the questioner, if he keeps them to train them for hunting, so that they are able to catch animals, then there is no sin in this, according to the Words of Allah, Most High:

"And those beasts and birds of prey which you have trained as hounds, training and teaching them (to catch) in the manner as directed to you by Allah; so eat of what they catch for you, but pronounce the Name of Allah over it, and fear Allah. Verily, Allah is Swift in reckoning."

However if he keeps them just for a hobby or pastime, then this is forbidden for him, and it is not allowed. Every day that he possesses them he loses a Qirat of his reward.

I would like to take this opportunity to draw your attention to what many of the luxuriously wealthy do. They keep dogs in their houses; indeed, they might even purchase them for high prices, in spite of the fact that the Prophet ﷺ said:
"Whoever imitates a people, he is one of them."

My advice to these brothers is to fear Allah, the Almighty, the All-Powerful and to preserve their money and their reward and their recompense from loss, and to abandon these dogs and repent to Allah, Most Glorified, Most High. And whoever repents, Allah turns to him with Forgiveness.
