'Abdullah bin SAahi and Nubayysah bin Mas'ud bin Zaid went o Khaibar, and at that time there was peace treaty. They went their separate ways to about their business, then Muhayysah came upon 'Abdullah in Sahl lying dead in a pool of blood. He buried him, then he came to AL-Madinah. 'Abdur-Rahman bin Sahi. Huwayysah, and Muhayysah came to the Messenger of Allah, and 'Abdur-Rehman started to speak, but he was the youngest of them, so the Messenger of Allah said: "Let the elders speak first." So he fell silent and they (the other two) spoke. The Messenger of Allah said: "Will you swear fifty oaths, then you will receive compensation or be entitled to retaliate?" They said: "O Messenger of Allah, how can we swear an oath when we did not witness, and did not see (what happened)?" He said: "The n can the Jews swear fifty oaths declaring their innocence?" They said: "O Messenger of Allah, how can we accept the oath of a disbelieving people?" So the Messenger of Allah paid the blood money himself. (Using translation from Nasāʾī 4714)  

عَنْ سَهْلِ بْنِ أَبِي حَثْمَةَ وَمُحَيِّصَةَ بْنِ مَسْعُودِ بْنِ زَيْدٍ أَنَّهُمَا أَتَيَا خَيْبَرَ وَهِيَ يَوْمَئِذٍ صَلَحٌ فَتَفَرَّقَا لِحَوَائِجِهِمْ فَأَتَى مُحَيِّصَةُ عَلَى عَبْدِ اللهِ بْنِ سَهْلٍ وَهُوَ يَتَشَحَّطُ فِي دَمِهِ قَتِيلًا فَدَفَنَهُ ثُمَّ قَدِمَ الْمَدِينَةَ وَانْطَلَقَ عَبْدُ الرَّحْمَنِ بْنُ سَهْلٍ وَحُوَيِّصَةُ وَمُحَيِّصَةُ إِلَى رَسُولِ اللهِ ﷺ فَذَهَبَ عَبْدُ الرَّحْمَنِ يَتَكَلَّمُ وَهُوَ أَحْدَثُ الْقَوْمِ سِنًّا فَقَالَ رَسُولُ اللهِ ﷺ «كَبِّرِ الْكُبْرَ» فَسَكَتُّ فَتَكَلَّمَا فَقَالَ رَسُولُ اللهِ ﷺ «أَتَحْلِفُونَ بِخَمْسِينَ مِنْكُمْ فَتَسْتَحِقُّونَ صَاحِبَكُمْ أَوْ قَاتَلَكُمْ» قَالُوا يَا رَسُولَ اللهِ كَيْفَ نَحْلِفُ وَلَمْ نَشْهَدْ وَلَمْ نَرَ؟ قَالَ أَتُبْرِئُكُمْ يَهُودُ بِخَمْسِينَ؟ قَالُوا يَا رَسُولَ اللهِ كَيْفَ نَأْخُذُ أَيْمَانَ قَوْمٍ كُفَّارٍ فَعَقَلَهُ رَسُولُ اللهِ ﷺ مِنْ عِنْدِهِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ خَالَفَهُ سَعِيدُ بْنُ عُبَيْدٍ فِي مَعْنَى الْحَدِيثِ  

(a man from the Ansar) that a number of people from his tribe went to Khaibar and dispersed, and then they found one of them murdered. They said to the people with whom the corpse had been found, "You have killed our companion!" Those people said, "Neither have we killed him, nor do we know his killer." The bereaved group went to the Prophet ﷺ and said, "O Messenger of Allah ﷺ! We went to Khaibar and found one of us murdered." The Prophet ﷺ said, "Let the older among you come forward and speak." Then the Prophet ﷺ said, to them, "Bring your proof against the killer." They said "We have no proof." The Prophet ﷺ said, "Then they (the defendants) will take an oath." They said, "We do not accept the oaths of the Jews." Messenger of Allah ﷺ did not like that the Blood-money of the killed one be lost without compensation, so he paid one-hundred camels out of the camels of Zakat (to the relatives of the deceased) as Diya (Blood-money). (Using translation from Bukhārī 6898)  

أَخْبَرَهُ أَنَّ نَفَرًا مِنْ قَوْمِهِ انْطَلَقُوا إِلَى خَيْبَرَ فَتَفَرَّقُوا فِيهَا فَوَجَدُوا أَحَدَهُمْ قَتِيلًا فَقَالُوا لِلَّذِينَ وَجَدُوهُ عِنْدَهُمْ قَتَلْتُمْ صَاحِبَنَا قَالُوا مَا قَتَلْنَا وَلَا عَلِمْنَا فَانْطَلَقُوا إِلَى نَبِيِّ اللهِ ﷺ فَقَالُوا يَا نَبِيَّ اللهِ انْطَلَقْنَا إِلَى خَيْبَرَ فَوَجَدْنَا أَحَدَنَا قَتِيلًا فَقَالَ رَسُولُ اللهِ ﷺ «الْكِبَرُ الْكِبَرُ» فَقَالَ لَهُمْ «تَأْتُونَ بِالْبَيِّنَةِ عَلَى مَنْ قَتَلَ» قَالُوا مَا لَنَا بَيِّنَةٌ قَالَ «فَيَحْلِفُونَ لَكُمْ» قَالُوا لَا نَرْضَى بِأَيْمَانِ الْيَهُودِ فَكَرِهَ رَسُولُ اللهِ ﷺ أَنْ يُبْطِلَ دَمَهُ فَوَدَاهُ مِائَةً مِنْ إِبِلِ الصَّدَقَةِ
