The people asked Sahl bin Saʿd As-Sa' idi "With what thing (medicine) was the wound of Allah's Apostle treated?" He replied, "There is none left (living) amongst the people who knows it better than. ʿAli used to bring water in his shield and Fatima (i.e. the Prophet's daughter) used to wash the blood off his face. Then a mat (of palm leaves) was burnt and its ash was inserted in the wound of Allah's Apostle."  

سَأَلُوا سَهْلَ بْنَ سَعْدٍ السَّاعِدِيَّ ؓ بِأَىِّ شَىْءٍ دُووِيَ جُرْحُ النَّبِيِّ ﷺ فَقَالَ مَا بَقِيَ مِنَ النَّاسِ أَحَدٌ أَعْلَمُ بِهِ مِنِّي كَانَ عَلِيٌّ يَجِيءُ بِالْمَاءِ فِي تُرْسِهِ وَكَانَتْ يَعْنِي فَاطِمَةَ تَغْسِلُ الدَّمَ عَنْ وَجْهِهِ وَأُخِذَ حَصِيرٌ فَأُحْرِقَ ثُمَّ حُشِيَ بِهِ جُرْحُ رَسُولِ اللَّهِ ﷺ
