Hadith 12:375
Waki’ narrated to us, from Hanzala, from Salim, from his father, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever acquires a dog, except for a hunting dog or a livestock dog, two qirats of his reward will be diminished every day." He said: And Salim said: And Abu Hurayrah said: "Or a farm dog."
