"When Allah granted His Messenger ﷺ victory over Makkah, he stood (to deliver an address) among the people. He thanked and praised Allah, then he said: 'And from whomever (one of his relatives) was killed, then he has two options to choose from: Either to pardon or that he be killed.'"  

الترمذي:١٤٠٥حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ وَيَحْيَى بْنُ مُوسَى قَالاَ حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ حَدَّثَنَا الأَوْزَاعِيُّ حَدَّثَنِي يَحْيَى بْنُ أَبِي كَثِيرٍ حَدَّثَنِي أَبُو سَلَمَةَ حَدَّثَنِي أَبُو هُرَيْرَةَ قَالَ

لَمَّا فَتَحَ اللَّهُ عَلَى رَسُولِهِ مَكَّةَ قَامَ فِي النَّاسِ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ وَمَنْ قُتِلَ لَهُ قَتِيلٌ فَهُوَ بِخَيْرِ النَّظَرَيْنِ إِمَّا أَنْ يَعْفُوَ وَإِمَّا أَنْ يَقْتُلَ قَالَ وَفِي الْبَابِ عَنْ وَائِلِ بْنِ حُجْرٍ وَأَنَسٍ وَأَبِي شُرَيْحٍ خُوَيْلِدِ بْنِ عَمْرٍو
