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 ﷺ كَتَبَ إِلَى يَهُودَ " أَنَّهُ قَدْ وُجِدَ بَيْنَ أَظْهُرِكُمْ قَتِيلٌ فَدُوهُ " . فَكَتَبُوا يَحْلِفُونَ بِاللَّهِ خَمْسِينَ يَمِينًا مَا قَتَلْنَاهُ وَلاَ عَلِمْنَا قَاتِلاً . قَالَ فَوَدَاهُ رَسُولُ اللَّهِ ﷺ مِنْ عِنْدِهِ مِائَةَ نَاقَةٍ .
