أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَمَرَ بِقَتْلِ الْكِلاَبِ غَيْرَ مَا اسْتَثْنَى مِنْهَا ‏.‏

It was narrated from Ibn 'Umar that: the Messenger of Allah commanded that dogs be killed, except those which were exempted.
