أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا مُعَاذُ بْنُ هِشَامٍ، قَالَ حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، عَنْ خِلاَسٍ، عَنْ أَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِذَا وَلَغَ الْكَلْبُ فِي إِنَاءِ أَحَدِكُمْ فَلْيَغْسِلْهُ سَبْعَ مَرَّاتٍ أُولاَهُنَّ بِالتُّرَابِ " .
Ishaq ibn Ibrahim informed us: Mu'adh ibn Hisham narrated to us; he said: My father narrated to me, from Qatadah, from Khilas, from Abu Rafi', from Abu Hurairah, that the Messenger of Allah (ﷺ) said: 'If a dog laps from the vessel of any one of you, let him wash it seven times, the first of them with earth.'
Translation notes
The complete chain is translated; the English witness gives only Abu Hurairah. The first of the seven washes is specified as being with earth.
