Ablution with water left over by a cat and the concession in that
Sunan Ibn Majah
حَدَّثَنَا عَمْرُو بْنُ رَافِعٍ، وَإِسْمَاعِيلُ بْنُ تَوْبَةَ، قَالاَ حَدَّثَنَا يَحْيَى بْنُ زَكَرِيَّا بْنِ أَبِي زَائِدَةَ، عَنْ حَارِثَةَ، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَتَوَضَّأُ أَنَا وَرَسُولُ اللَّهِ، ـ صلى الله عليه وسلم ـ مِنْ إِنَاءٍ وَاحِدٍ قَدْ أَصَابَتْ مِنْهُ الْهِرَّةُ قَبْلَ ذَلِكَ .
It was narrated that 'Aishah said: "The Messenger of Allah and I used to perform ablution from a single vessel, when the cat had drunk from it beforehand."
