Sahih al-Bukhari
Sahih al-Bukhari 2903
حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، حَدَّثَنَا يَعْقُوبُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلٍ، قَالَ لَمَّا كُسِرَتْ بَيْضَةُ النَّبِيِّ صلى الله عليه وسلم عَلَى رَأْسِهِ وَأُدْمِيَ وَجْهُهُ، وَكُسِرَتْ رَبَاعِيَتُهُ، وَكَانَ عَلِيٌّ يَخْتَلِفُ بِالْمَاءِ فِي الْمِجَنِّ، وَكَانَتْ فَاطِمَةُ تَغْسِلُهُ، فَلَمَّا رَأَتِ الدَّمَ يَزِيدُ عَلَى الْمَاءِ كَثْرَةً عَمَدَتْ إِلَى حَصِيرٍ، فَأَحْرَقَتْهَا وَأَلْصَقَتْهَا عَلَى جُرْحِهِ، فَرَقَأَ الدَّمُ.
Sahl reported: When the Prophet’s ﷺ helmet was struck and broken on his head, his face was bloodied, and one of his rubaʿiyya teeth was broken, Ali brought water in his shield while Fatima washed him. When she saw that the blood exceeded the water, she took a mat, burned it, and pressed its ashes onto his wound. The bleeding stopped.
Translation notes
The Arabic names the broken tooth as a rubaʿiyya; the English witness calls it a front tooth. The Arabic term is retained pending confirmation of its precise modern dental equivalent.
وَكُسِرَتْ رَبَاعِيَتُهُ
The Arabic specifies a rubaʿiyya tooth; the English witness renders this as a front tooth, and the exact modern dental equivalent has not been established here.
What is the most accurate natural English rendering of rubaʿiyya in this context?
