Hadith 5849
وَعَنْ أَنَسٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كُسِرَتْ رَبَاعِيَتُهُ يَوْمَ أُحُدٍ وَشُجَّ رَأْسِهِ فَجَعَلَ يَسْلُتُ الدَّمَ عَنْهُ وَيَقُولُ: «كَيْفَ يُفْلِحُ قَوْمٌ شَجُّوا رَأْسَ نَبِيِّهِمْ وَكَسَرُوا رَبَاعِيَتَهُ» . رَوَاهُ مُسلم
Anas told that when one of God's messenger's teeth between the front and the canine teeth was broken at the battle of Uhud and a cut was made in his head, he began to remove the blood from himself and say, "How can a people who have split the head of their prophet and broken his tooth next to his eyetooth prosper?'' Muslim transmitted it.
