حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا يَعْقُوبُ، عَنْ أَبِي حَازِمٍ، أَنَّهُ سَمِعَ سَهْلَ بْنَ سَعْدٍ، وَهْوَ يُسْأَلُ عَنْ جُرْحِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ أَمَا وَاللَّهِ إِنِّي لأَعْرِفُ مَنْ كَانَ يَغْسِلُ جُرْحَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَمَنْ كَانَ يَسْكُبُ الْمَاءَ وَبِمَا دُووِيَ ـ قَالَ كَانَتْ فَاطِمَةُ ـ عَلَيْهَا السَّلاَمُ ـ بِنْتُ رَسُولِ اللَّهِ صلى الله عليه وسلم تَغْسِلُهُ وَعَلِيٌّ يَسْكُبُ الْمَاءَ بِالْمِجَنِّ، فَلَمَّا رَأَتْ فَاطِمَةُ أَنَّ الْمَاءَ لاَ يَزِيدُ الدَّمَ إِلاَّ كَثْرَةً أَخَذَتْ قِطْعَةً مِنْ حَصِيرٍ، فَأَحْرَقَتْهَا وَأَلْصَقَتْهَا فَاسْتَمْسَكَ الدَّمُ، وَكُسِرَتْ رَبَاعِيَتُهُ يَوْمَئِذٍ، وَجُرِحَ وَجْهُهُ، وَكُسِرَتِ الْبَيْضَةُ عَلَى رَأْسِهِ‏.‏

Narrated Abu Hazim:That he heard Sahl bin Sa`d being asked about the wounds of Allah's Messenger (ﷺ) saying, "By Allah, I know who washed the wounds of Allah's Messenger (ﷺ) and who poured water (for washing them), and with what he was treated." Sahl added, "Fatima, the daughter of Allah's Messenger (ﷺ) used to wash the wounds, and `Ali bin Abi Talib used to pour water from a shield. When Fatima saw that the water aggravated the bleeding, she took a piece of a mat, burnt it, and inserted its ashes into the wound so that the blood was congealed (and bleeding stopped). His canine tooth got broken on that day, and his face was wounded, and his helmet was broken on his head
