It was narrated from Sa'eed bin 'Ubaid At-Ta'l from Bushair bin Yasar who said:

"A man from among the Ansar who was called Sahl bin Abi Hathmah told him that some of his people went to Khaibar, where they went their separate ways. Then they found one of their numbers slain. They said to those in whose land they found him: 'You killed our companion!' They said: 'We did not kill him and we do not know who killed him.' They went to the prophet of Allah and said: 'O Prophet of Allah, we went to Khaibar and we found one of our number slain.' The Messenger of Allah said: 'Let the elders speak first.' And he said to them: 'Bring proof of the one whom you suspect killed him.' They said: 'We do not have any proof.' He said: "Then let them swear an oath to you.' They said" 'We will not accept the oath of the Jews.' The Messenger of Allah did not want his blood to have been shed with no Justice done, so he paid a Diyah of one hundred camels from the Sadaqah." 'Amr bin Shu'aib differed with them.

أَخْبَرَنَا أَحْمَدُ بْنُ سُلَيْمَانَ، قَالَ حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ عُبَيْدٍ الطَّائِيُّ، عَنْ بُشَيْرِ بْنِ يَسَارٍ، زَعَمَ أَنَّ رَجُلاً، مِنَ الأَنْصَارِ يُقَالُ لَهُ سَهْلُ بْنُ أَبِي حَثْمَةَ أَخْبَرَهُ أَنَّ نَفَرًا مِنْ قَوْمِهِ انْطَلَقُوا إِلَى خَيْبَرَ فَتَفَرَّقُوا فِيهَا فَوَجَدُوا أَحَدَهُمْ قَتِيلاً فَقَالُوا لِلَّذِينَ وَجَدُوهُ عِنْدَهُمْ قَتَلْتُمْ صَاحِبَنَا قَالُوا مَا قَتَلْنَاهُ وَلاَ عَلِمْنَا قَاتِلاً . فَانْطَلَقُوا إِلَى نَبِيِّ اللَّهِ ﷺ فَقَالُوا يَا نَبِيَّ اللَّهِ انْطَلَقْنَا إِلَى خَيْبَرَ فَوَجَدْنَا أَحَدَنَا قَتِيلاً . فَقَالَ رَسُولُ اللَّهِ ﷺ " الْكُبْرَ الْكُبْرَ " . فَقَالَ لَهُمْ " تَأْتُونَ بِالْبَيِّنَةِ عَلَى مَنْ قَتَلَ " . قَالُوا مَا لَنَا بَيِّنَةٌ . قَالَ " فَيَحْلِفُونَ لَكُمْ " . قَالُوا لاَ نَرْضَى بِأَيْمَانِ الْيَهُودِ . وَكَرِهَ رَسُولُ اللَّهِ ﷺ أَنْ يَبْطُلَ دَمُهُ فَوَدَاهُ مِائَةً مِنْ إِبِلِ الصَّدَقَةِ . خَالَفَهُمْ عَمْرُو بْنُ شُعَيْبٍ .
