Sahih al-Bukhari 243
In-book no 243حَدَّثَنَا مُحَمَّدٌ، قَالَ أَخْبَرَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي حَازِمٍ، سَمِعَ سَهْلَ بْنَ سَعْدٍ السَّاعِدِيَّ،، وَسَأَلَهُ النَّاسُ، وَمَا بَيْنِي وَبَيْنَهُ أَحَدٌ بِأَىِّ شَىْءٍ دُووِيَ جُرْحُ النَّبِيِّ صلى الله عليه وسلم فَقَالَ مَا بَقِيَ أَحَدٌ أَعْلَمُ بِهِ مِنِّي، كَانَ عَلِيٌّ يَجِيءُ بِتُرْسِهِ فِيهِ مَاءٌ، وَفَاطِمَةُ تَغْسِلُ عَنْ وَجْهِهِ الدَّمَ، فَأُخِذَ حَصِيرٌ فَأُحْرِقَ فَحُشِيَ بِهِ جُرْحُهُ.
Narrated Abu Hazim: Sahl bin Sa`d As-Sa`idi, was asked by the people, "With what was the wound of the Prophet (ﷺ) treated? Sahl replied, "None remains among the people living who knows that better than I. `Ali used to bring water in his shield and Fatima used to wash the blood off his face. Then straw mat was burnt and the wound was filled with it."
