أَخْبَرَنَا عَمْرُو بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا هِشَامُ بْنُ عَبْدِ الْمَلِكِ، قَالَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا جَابِرُ بْنُ صُبْحٍ، قَالَ سَمِعْتُ خِلاَسَ بْنَ عَمْرٍو، يَقُولُ سَمِعْتُ عَائِشَةَ، تَقُولُ كُنْتُ أَنَا وَرَسُولُ اللَّهِ، صلى الله عليه وسلم أَبُو الْقَاسِمِ فِي الشِّعَارِ الْوَاحِدِ وَأَنَا حَائِضٌ، طَامِثٌ فَإِنْ أَصَابَهُ مِنِّي شَىْءٌ غَسَلَ مَا أَصَابَهُ لَمْ يَعْدُهُ إِلَى غَيْرِهِ وَصَلَّى فِيهِ ثُمَّ يَعُودُ مَعِي فَإِنْ أَصَابَهُ مِنِّي شَىْءٌ فَعَلَ مِثْلَ ذَلِكَ لَمْ يَعْدُهُ إِلَى غَيْرِهِ ‏.‏

Khilas bin 'Amr said:"I heard Aisha (ra) say: 'The Messenger of Allah (ﷺ), Abii Al-Qbim, and I were beneath a single blanket, and I was menstruating. If something got on him from me, he would wash whatever had got on him and he did not wash anywhere else, and he prayed in it then came back to me.And if anything got on him from me,he would do exactly the same and he did not wash anywhere else
