BAYHAQI 1143:
from Abū Hurayrah —
[Machine] He said: The Messenger of Allah ﷺ said: "The purification of the vessel of one of you, if a dog licks in it, is to wash it seven times, the first of which is with soil." And Abu Abdullah Al-Hafiz told us, narrating from Ahmad bin Ja'far Al-Qatti'i, narrating from Abdullah bin Ahmad bin Hanbal, who narrated from my father, narrating from Ismail, who narrated from Hisham bin Hassaan, who mentioned it with a similar narration.

عن ابو هريره —
أَنَّهُ قَالَ قَالَ رَسُولُ اللهِ ﷺ طَهُورُ إِنَاءِ أَحَدِكُمْ إِذَا وَلَغَ الْكَلْبُ فِيهِ أَنْ يَغْسِلَهُ سَبْعَ مَرَّاتٍ أُولَاهُنَّ بِالتُّرَابِ 1144 وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَحْمَدُ بْنُ جَعْفَرٍ الْقَطِيعِيُّ ثنا عَبْدُ اللهِ بْنُ أَحْمَدَ بْنِ حَنْبَلٍ حَدَّثَنِي أَبِي ثنا إِسْمَاعِيلُ عَنْ هِشَامِ بْنِ حَسَّانَ عَنِ ابْنِ سِيرِينَ فَذَكَرَهُ بِمِثْلِهِ
