Washing a vessel that has been licked by a dog
Sunan Ibn Majah
حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ " إِذَا شَرِبَ الْكَلْبُ فِي إِنَاءِ أَحَدِكُمْ فَلْيَغْسِلْهُ سَبْعَ مَرَّاتٍ " .
It was narrated from Abu Hurairah that: The Messenger of Allah said: "If a dog licks the vessel of anyome of you, let him wash it seven times."
