Narrated Abu Huraira (rad):
Narrated by Abu Huraira (rad): Allah’s Messenger (ﷺ) said: “The cleansing of the utensil belonging to one of you, after it has been licked by a dog, is to wash it seven times, and using soil for cleaning at the first time.” [Muslim reported it].
وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ طَهُورُ إِنَاءِ أَحَدِكُمْ إِذْ وَلَغَ فِيهِ اَلْكَلْبُ أَنْ يَغْسِلَهُ سَبْعَ مَرَّاتٍ, أُولَاهُنَّ بِالتُّرَابِ } أَخْرَجَهُ مُسْلِمٌ 1‏ .‏
