The Prophet ﷺ said: No recompense may be demanded if the fire spreads.  

قَالَ رَسُولُ اللَّهِ ﷺ النَّارُ جُبَارٌ  

Al-Rubayyi', sister of Anas b. al-Nadr, broke (one of) the front teeth of a woman. They came to the Prophet ﷺ. He made a decision in accordance with the Book of Allah that retaliation should be taken. Anas b. al-Nadr said: I swear by Him who has sent you the truth, her front tooth will not be broken today. He replied: Anas ! Allah's decree is retaliation. But the people were agreeable to accepting a fine, so the Prophet ﷺ said: Among Allah's servants there are those who, if they adjured Allah, He (Allah) would consent to it. Abu Dawud said: I heard Ahmad b. Hanbal say: He was asked : How retaliation of a tooth is taken ? He said: It is broken with a file.  

كَسَرَتِ الرُّبَيِّعُ أُخْتُ أَنَسِ بْنِ النَّضْرِ ثَنِيَّةَ امْرَأَةٍ فَأَتَوُا النَّبِيَّ ﷺ فَقَضَى بِكِتَابِ اللَّهِ الْقِصَاصَ فَقَالَ أَنَسُ بْنُ النَّضْرِ وَالَّذِي بَعَثَكَ بِالْحَقِّ لاَ تُكْسَرُ ثَنِيَّتُهَا الْيَوْمَ قَالَ يَا أَنَسُ كِتَابُ اللَّهِ الْقِصَاصُ فَرَضُوا بِأَرْشٍ أَخَذُوهُ فَعَجِبَ نَبِيُّ اللَّهِ ﷺ وَقَالَ إِنَّ مِنْ عِبَادِ اللَّهِ مَنْ لَوْ أَقْسَمَ عَلَى اللَّهِ لأَبَرَّهُ
