Sahih al-Bukhari, Book 87, Hadith 32 (In-Book) ⓘ
Narrated Anas: The daughter of An-Nadr slapped a girl and broke her incisor tooth. They (the relatives of that girl), came to the Prophet and he gave the order of Qisas (equality in punishment).
حَدَّثَنَا الأَنْصَارِيُّ، حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسٍ ـ رضى الله عنه ـ أَنَّ ابْنَةَ النَّضْرِ، لَطَمَتْ جَارِيَةً، فَكَسَرَتْ ثَنِيَّتَهَا، فَأَتَوُا النَّبِيَّ صلى الله عليه وسلم فَأَمَرَ بِالْقِصَاصِ.
