باب غَزْوَةُ خَيْبَرَ
Sahih al-Bukhari 4239

Narrated Sa`id:

Aban bin Sa`id came to the Prophet (ﷺ) and greeted him. Abu Huraira said, "O Allah's Messenger (ﷺ)! This (Aban) is the murderer of the Ibn Qauqal." (On hearing that), Aban said to Abu Huraira, "How strange your saying is! You, a guinea pig, descending from Qadum Dan, blaming me for (killing) a person whom Allah favored (with martyrdom) with my hand, and whom He forbade to degrade me with his hand.'

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَمْرُو بْنُ يَحْيَى بْنِ سَعِيدٍ، قَالَ أَخْبَرَنِي جَدِّي، أَنَّ أَبَانَ بْنَ سَعِيدٍ، أَقْبَلَ إِلَى النَّبِيِّ صلى الله عليه وسلم فَسَلَّمَ عَلَيْهِ، فَقَالَ أَبُو هُرَيْرَةَ يَا رَسُولَ اللَّهِ هَذَا قَاتِلُ ابْنِ قَوْقَلٍ‏.‏ وَقَالَ أَبَانُ لأَبِي هُرَيْرَةَ وَاعَجَبًا لَكَ وَبْرٌ تَدَأْدَأَ مِنْ قَدُومِ ضَأْنٍ‏.‏ يَنْعَى عَلَىَّ امْرَأً أَكْرَمَهُ اللَّهُ بِيَدِي، وَمَنَعَهُ أَنْ يُهِينَنِي بِيَدِهِ‏.‏
