حَدَّثَنَا يَحْيَى بْنُ يَحْيَى التَّمِيمِىُّ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِى حَازِمٍ عَنْ أَبِيهِ أَنَّهُ سَمِعَ سَهْلَ بْنَ سَعْدٍ يُسْأَلُ عَنْ جُرْحِ رَسُولِ اللَّهِ -صلى الله عليه وسلم- يَوْمَ أُحُدٍ فَقَالَ جُرِحَ وَجْهُ رَسُولِ اللَّهِ -صلى الله عليه وسلم- وَكُسِرَتْ رَبَاعِيَتُهُ وَهُشِمَتِ الْبَيْضَةُ عَلَى رَأْسِهِ فَكَانَتْ فَاطِمَةُ بِنْتُ رَسُولِ اللَّهِ -صلى الله عليه وسلم- تَغْسِلُ الدَّمَ وَكَانَ عَلِىُّ بْنُ أَبِى طَالِبٍ يَسْكُبُ عَلَيْهَا بِالْمِجَنِّ فَلَمَّا رَأَتْ فَاطِمَةُ أَنَّ الْمَاءَ لاَ يَزِيدُ الدَّمَ إِلاَّ كَثْرَةً أَخَذَتْ قِطْعَةَ حَصِيرٍ فَأَحْرَقَتْهُ حَتَّى صَارَ رَمَادًا ثُمَّ أَلْصَقَتْهُ بِالْجُرْحِ فَاسْتَمْسَكَ الدَّمُ.

'Abdul' Aziz bin Abi Hazim narrated that his father heard Sahl bin Sa'd being asked about the wounds sustained by the Messenger of Allah (s.a.w) on the day of (the battle of) Uhud. He said: The face of the Messenger of Allah (s.a.w) was wounded and his front tooth was broken, and his helmet was crushed on his head. Fatimah, the daughter of the Messenger of Allah (s.a.w), was washing away the blood, and 'Ali bin Abi Talib was pouring water on it from a shield. When Fatimah saw that the water was only making the bleeding worse, she took a piece of reed mat and burnt it until it turned to ashes, then she placed it on the wound and the bleeding stopped.
