وَعَنْ أَنَسٍ رضى الله عنه
«أَنَّ اَلرُّبَيِّعَ بِنْتَ اَلنَّضْرِ (عَمَّتَهُ) كَسَرَتْ ثَنِيَّةَ جَارِيَةٍ، فَطَلَبُوا إِلَيْهَا اَلْعَفْوَ، فَأَبَوْا، فَعَرَضُوا اَلْأَرْشَ، فَأَبَوْا، فَأَتَوْا رَسُولَ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ (وَأَبَوْا إِلَّا اَلْقِصَاصَ، فَأَمَرَ رَسُولُ اَللَّهِ) صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالْقِصَاصِ، فَقَالَ أَنَسُ بْنُ اَلنَّضْرِ: يَا رَسُولَ اَللَّهِ!
أَتُكْسَرُ ثَنِيَّةُ اَلرُّبَيِّعِ? لَا، وََالَّذِي بَعَثَكَ بِالْحَقِّ، لَا تُكْسَرُ ثَنِيَّتُهَا، فَقَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«يَا أَنَسُ! كِتَابُ اَللَّهِ: اَلْقِصَاصُ». فَرَضِيَ اَلْقَوْمُ، فَعَفَوْا، فَقَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -: «إِنَّ مِنْ عِبَادِ اَللَّهِ مَنْ لَوْ أَقْسَمَ عَلَى اَللَّهِ لَأَبَرَّهُ»
Ar-Rubai bint an-Nadr (his aunt) broke the incisor teeth of a girl. The family of Ar·Rubai asked the family of the girl to pardon her, but they refused. They then offered them Arsh, (as compensation) but they also refused. They came to the Messenger of Allah (sallallahu alayhi wa sallam) asking for Qisas, and he gave orders that they should take their Qisas from Ar-Rubai.
Anas ibn an-Nadr then came to the Messenger of Allah (sallallahu alayhi wa sallam) and said, ‘O Messenger ofAllah! 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. The Messenger of Allah (sallallahu alayhi wa sallam) then said to him, “Anas! Allah’s decree is equal retaliation.”
But the family of the girl agreed to pardon Ar-Rubai. The Messenger of Allah (sallallahu alayhi wa sallam) then said, “Among Allah’s servants are those who if they swear by Allah (for something), Allah will consent to their oath.” Agreed upon, and the wording is from Al·Bukhari.
