Messenger of Allah ﷺ (pointing to his broken canine tooth) said, "Allah's Wrath has become severe on the people who harmed His Prophet. Allah's Wrath has become severe on the man who is killed by the Apostle of Allah in Allah's Cause."  

قَالَ رَسُولُ اللَّهِ ﷺ اشْتَدَّ غَضَبُ اللَّهِ عَلَى قَوْمٍ فَعَلُوا بِنَبِيِّهِ يُشِيرُ إِلَى رَبَاعِيَتِهِ اشْتَدَّ غَضَبُ اللَّهِ عَلَى رَجُلٍ يَقْتُلُهُ رَسُولُ اللَّهِ ﷺ فِي سَبِيلِ اللَّهِ  

Allah's Wrath became severe on him whom the Prophet ﷺ had killed in Allah's Cause. Allah's Wrath became severe on the people who caused the face of Allah's Prophet to bleed.  

اشْتَدَّ غَضَبُ اللَّهِ عَلَى مَنْ قَتَلَهُ النَّبِيُّ ﷺ فِي سَبِيلِ اللَّهِ اشْتَدَّ غَضَبُ اللَّهِ عَلَى قَوْمٍ دَمَّوْا وَجْهَ نَبِيِّ اللَّهِ ﷺ  

That he heard Sahl bin Saʿd being asked about the wounds of Messenger of Allah ﷺ saying, "By Allah, I know who washed the wounds of Messenger of Allah ﷺ and who poured water (for washing them), and with what he was treated." Sahl added, "Fatima, the daughter of Messenger of Allah ﷺ used to wash the wounds, and ʿAli 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 face was wounded, and his helmet was broken on his head."  

عَنْ جُرْحِ رَسُولِ اللَّهِ ﷺ فَقَالَ أَمَا وَاللَّهِ إِنِّي لأَعْرِفُ مَنْ كَانَ يَغْسِلُ جُرْحَ رَسُولِ اللَّهِ ﷺ وَمَنْ كَانَ يَسْكُبُ الْمَاءَ وَبِمَا دُووِيَ قَالَ كَانَتْ فَاطِمَةُ عَلَيْهَا السَّلاَمُ بِنْتُ رَسُولِ اللَّهِ ﷺ 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  

Allah's Wrath gets severe on a person killed by a prophet, and Allah's Wrath became severe on him who had caused the face of Messenger of Allah ﷺ to bleed.  

اشْتَدَّ غَضَبُ اللَّهِ عَلَى مَنْ قَتَلَهُ نَبِيٌّ اشْتَدَّ غَضَبُ اللَّهِ عَلَى مَنْ دَمَّى وَجْهَ رَسُولِ اللَّهِ ﷺ
