عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا شَرِبَ الْكَلْبُ فِي إِنَاء أحدكُم فليغسله سبع مَرَّات» وَفِى رِوَايَةٍ لِمُسْلِمٍ: «طَهُورُ إِنَاءِ أَحَدِكُمْ إِذَا وَلَغَ فِيهِ الْكَلْبُ أَنْ يَغْسِلَهُ سَبْعَ مَرَّاتٍ أولَاهُنَّ بِالتُّرَابِ»

Umm Qais daughter of Mihsan told how she brought a young son of hers who was not yet weaned to God’s messenger. He set him on his lap, and the child passed water on his garment; so he called for water and sprinkled it, but did not wash it. (Bukhari and Muslim.)
