Sahih al-Bukhari 67:181
Narrated Abu Hazim:
The people differed about the type of treatment which had been given to Allah's Messenger (ﷺ) on the day (of the battle) of Uhud. So they asked Sahl bin Sa`d As-Sa`id who was the only surviving Companion (of the Prophet) at Medina. He replied, "Nobody Is left at Medina who knows it better than I. Fatima was washing the blood off his face and `Ali was bringing water in his shield, and then a mat of datepalm leaves was burnt and (the ash) was inserted into the wound."

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي حَازِمٍ، قَالَ اخْتَلَفَ النَّاسُ بِأَىِّ شَىْءٍ دُووِيَ جُرْحُ رَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ أُحُدٍ، فَسَأَلُوا سَهْلَ بْنَ سَعْدٍ السَّاعِدِيَّ، وَكَانَ مِنْ آخِرِ مَنْ بَقِيَ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم بِالْمَدِينَةِ، فَقَالَ وَمَا بَقِيَ مِنَ النَّاسِ أَحَدٌ أَعْلَمُ بِهِ مِنِّي، كَانَتْ فَاطِمَةُ عَلَيْهَا السَّلاَمُ تَغْسِلُ الدَّمَ عَنْ وَجْهِهِ، وَعَلِيٌّ يَأْتِي بِالْمَاءِ عَلَى تُرْسِهِ، فَأُخِذَ حَصِيرٌ، فَحُرِّقَ فَحُشِيَ بِهِ جُرْحُهُ.
