Hadith
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ حُمَيْدَةَ بِنْتِ عُبَيْدِ بْنِ رِفَاعَةَ، عَنْ كَبْشَةَ بِنْتِ كَعْبِ بْنِ مَالِكٍ، - وَكَانَتْ تَحْتَ ابْنِ أَبِي قَتَادَةَ - أَنَّ أَبَا قَتَادَةَ، دَخَلَ فَسَكَبَتْ لَهُ وَضُوءًا فَجَاءَتْ هِرَّةٌ فَشَرِبَتْ مِنْهُ فَأَصْغَى لَهَا الإِنَاءَ حَتَّى شَرِبَتْ قَالَتْ كَبْشَةُ فَرَآنِي أَنْظُرُ إِلَيْهِ فَقَالَ أَتَعْجَبِينَ يَا ابْنَةَ أَخِي فَقُلْتُ نَعَمْ . فَقَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّهَا لَيْسَتْ بِنَجَسٍ إِنَّهَا مِنَ الطَّوَّافِينَ عَلَيْكُمْ وَالطَّوَّافَاتِ " .
Narrated AbuQatadah: Kabshah, daughter of Ka'b ibn Malik and wife of Ibn AbuQatadah, reported: AbuQatadah visited (me) and I poured out water for him for ablution. A cat came and drank some of it and he tilted the vessel for it until it drank some of it. Kabshah said: He saw me looking at him; he asked me: Are you surprised, my niece? I said: Yes. He then reported the Messenger of Allah (ﷺ) as saying: It is not unclean; it is one of those (males or females) who go round among you
