أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ أَنْبَأَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنِ الأَعْمَشِ، 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 مَرَّاتٍ " .
Ali ibn Hujr informed us: Ali ibn Mushir narrated to us, from al-A'mash, from Abu Razin and Abu Salih, from Abu Hurairah, who said: The Messenger of Allah (ﷺ) said: 'If a dog laps from the vessel of any one of you, let him pour out its contents, then wash it seven times.'
