Sahih Muslim · Book 2: The Book of Purification · Rulings on what was licked by a dog
Ibn Mughaffal reported:
وَحَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا شُعْبَةُ ، عَنْ أَبِي التَّيَّاحِ ، سَمِعَ مُطَرِّفَ بْنَ عَبْدِ اللَّهِ ، يُحَدِّثُ عَنِ ابْنِ الْمُغَفَّلِ ، قَالَ أَمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِقَتْلِ الْكِلاَبِ ثُمَّ قَالَ " مَا بَالُهُمْ وَبَالُ الْكِلاَبِ " . ثُمَّ رَخَّصَ فِي كَلْبِ الصَّيْدِ وَكَلْبِ الْغَنَمِ وَقَالَ " إِذَا وَلَغَ الْكَلْبُ فِي الإِنَاءِ فَاغْسِلُوهُ سَبْعَ مَرَّاتٍ وَعَفِّرُوهُ الثَّامِنَةَ فِي التُّرَابِ " .
The Messenger of Allah (ﷺ) ordered killing of the dogs, and then said: What about them, i. e. about other dogs? and then granted concession (to keep) the dog for hunting and the dog for (the security) of the herd, and said: When the dog licks the utensil, wash it seven times, and rub it with earth the eighth time.
