كتاب الذبائح والصيد
Read the English translation first, with the original Arabic directly underneath.
Narrated Ibn `Umar:
The Prophet (ﷺ) said, "Whoever keeps a (pet) dog which is neither a watch dog nor a hunting dog, will get a daily deduction of two Qirat from his good deeds."
مَنِ اقْتَنَى كَلْبًا لَيْسَ بِكَلْبِ مَاشِيَةٍ أَوْ ضَارِيَةٍ، نَقَصَ كُلَّ يَوْمٍ مِنْ عَمَلِهِ قِيرَاطَانِ
