وَعَنْ أَبِي شُرَيْحٍ اَلْخُزَاعِيِّ
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«فَمَنْ قُتِلَ لَهُ قَتِيلٌ بَعْدَ مَقَالَتِي هَذِهِ، فَأَهْلُهُ بَيْنَ خِيَرَتَيْنِ: إِمَّا أَنْ يَأْخُذُوا اَلْعَقْلِ. أَوْ يَقْتُلُوا»
“If the relative of one of you is killed after my speech, his family has one of two choices: ‘Either they take his Diyah or kill the killer.’ Related by Abu Dawud and An-Nasai.”
