Narrated 'Abd al-Rahman b. Bujaid:

I swear by Allah, Sahl had a misunderstanding about this tradition. The Messenger of Allah (ﷺ) wrote to the Jews: A slain man has been found amongnst you, so pay his bloodwit. They wrote (to him): Swearing by Allah fifty oaths, we neither killed him nor do we know his slayer. He said: Then the Messenger of Allah (ﷺ) himself paid his bloodwit which consisted of one hundred she-camels.

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ يَحْيَى الْحَرَّانِيُّ، حَدَّثَنِي مُحَمَّدٌ، - يَعْنِي ابْنَ سَلَمَةَ - عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ بْنِ الْحَارِثِ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ بُجَيْدٍ، قَالَ إِنَّ سَهْلاً وَاللَّهِ أَوْهَمَ الْحَدِيثَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَتَبَ إِلَى يَهُودَ ‏

‏ أَنَّهُ قَدْ وُجِدَ بَيْنَ أَظْهُرِكُمْ قَتِيلٌ فَدُوهُ ‏

‏ ‏.‏ فَكَتَبُوا يَحْلِفُونَ بِاللَّهِ خَمْسِينَ يَمِينًا مَا قَتَلْنَاهُ وَلاَ عَلِمْنَا قَاتِلاً ‏.‏ قَالَ فَوَدَاهُ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنْ عِنْدِهِ مِائَةَ نَاقَةٍ ‏.‏
