كتاب الصيد والذبائح
Read the English translation first, with the original Arabic directly underneath.
It was narrated from Salim, from his father, that the Messenger of Allah said:
"Whoever keeps a dog. Except a dog for hunting or herding livestock, two Qirats will be deducted from his reward each day."
مَنِ اقْتَنَى كَلْبًا إِلاَّ كَلْبَ صَيْدٍ أَوْ مَاشِيَةٍ نَقَصَ مِنْ أَجْرِهِ كُلَّ يَوْمٍ قِيرَاطَانِ
