Sahih Bukhari 4500

حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُنِيرٍ , سَمِعَ عَبْدَ اللَّهِ بْنَ بَكْرٍ السَّهْمِيَّ , حَدَّثَنَا حُمَيْدٌ , عَنْ أَنَسٍ : أَنَّ الرُّبَيِّعَ عَمَّتَهُ ، كَسَرَتْ ثَنِيَّةَ جَارِيَةٍ ، فَطَلَبُوا إِلَيْهَا الْعَفْوَ ، فَأَبَوْا فَعَرَضُوا الْأَرْشَ ، فَأَبَوْا فَأَتَوْا رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَبَوْا إِلَّا الْقِصَاصَ ، فَأَمَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالْقِصَاصِ ، فَقَالَ أَنَسُ بْنُ النَّضْرِ : يَا رَسُولَ اللَّهِ , أَتُكْسَرُ ثَنِيَّةُ الرُّبَيِّعِ لَا ، وَالَّذِي بَعَثَكَ بِالْحَقِّ لَا تُكْسَرُ ثَنِيَّتُهَا , فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : يَا أَنَسُ ,كِتَابُ اللَّهِ الْقِصَاصُ ، فَرَضِيَ الْقَوْمُ فَعَفَوْا ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : إِنَّ مِنْ عِبَادِ اللَّهِ مَنْ لَوْ أَقْسَمَ عَلَى اللَّهِ لَأَبَرَّهُ .

Narrated Anas: That his aunt, Ar-Rubai' broke an incisor tooth of a girl. My aunt's family requested the girl's relatives for forgiveness but they refused; then they proposed a compensation, but they refused. Then they went to Allah's Messenger and refused everything except Al-Qisas (i.e. equality in punishment). So Allah's Apostle passed the judgment of Al-Qisas (i.e. equality of punishment). Anas bin Al-Nadr said, O Allah's Messenger ! Will the incisor tooth of Ar-Rubai be broken? No, by Him Who sent you with the Truth, her incisor tooth will not be broken. Allah's Messenger said, O Anas! The prescribed law of Allah is equality in punishment (i.e. Al-Qisas.) Thereupon those people became satisfied and forgave her. Then Allah's Messenger said, Among Allah's Worshippers there are some who, if they took Allah's Oath (for something), Allah fulfill their oaths.
