Rulings on what was licked by a dog
Sahih Muslim
وَحَدَّثَنِي عَلِيُّ بْنُ حُجْرٍ السَّعْدِيُّ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، أَخْبَرَنَا الأَعْمَشُ، عَنْ أَبِي رَزِينٍ، وَأَبِي، صَالِحٍ عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا وَلَغَ الْكَلْبُ فِي إِنَاءِ أَحَدِكُمْ فَلْيُرِقْهُ ثُمَّ لْيَغْسِلْهُ سَبْعَ مِرَارٍ " .
Abu Huraira reported the Messenger of Allah (ﷺ) to have said: When a dog licks a utensil belonging to any one of you, (the thing contained in it) should be thrown away and then (the utensil) should be washed seven times.
