Arabic (Original)
حَدَّثَنَا إِسْحَاقُ أَخْبَرَنَا مَالِكٌ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ بِقَتْلِ الْكِلَابِ وَقَالَ مَنْ اقْتَنَى كَلْبًا إِلَّا كَلْبَ مَاشِيَةٍ أَوْ ضَارِيَةٍ نَقَصَ مِنْ عَمَلِهِ كُلَّ يَوْمٍ قِيرَاطَانِ.
English Translation
Ishaq told us, Malik informed us, from Nafi', from Ibn Umar, that the Messenger of Allah, peace and blessings be upon him, ordered the killing of dogs and said: "Whoever keeps a dog, except a dog for herding livestock or a hunting dog, loses two qirats from his good deeds every day."
