Tooth for tooth
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.
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 (ﷺ) and he gave the order of Qisas (equality in punishment).
