The eldest one (eldest in regard to age should speak). So he kept quiet, and his companions (Muhayyisa and Huwayyisa) began to speak, and he ('Abd al Rahman) spoke along with them and they narrated to Messenger of Allah ﷺ the murder of 'Abdullah b. Sahl. Thereupon he said to them: Are you prepared to take fifty oaths so that you may be entitled (to blood-wit) of your companion (or your man who has murdered)? They said: How can we take an oath on a matter which we have not witnessed? He (the Holy Prophet) said: Then the Jews will exonerate themselves by fifty oaths. They said: How can we accept the oaths of people who are unbelievers? When Messenger of Allah ﷺ saw that, he himself paid his blood-wit. (Using translation from Muslim 1669a)
أَنَّهُ قَالَ وَعَنْ رَافِعِ بْنِ خَدِيجٍ أَنَّهُمَا قَالَا خَرَجَ عَبْدُ اللهِ بْنُ سَهْلِ بْنِ زَيْدٍ وَمُحَيِّصَةُ بْنُ مَسْعُودٍ حَتَّى إِذَا كَانَا بِخَيْبَرَ تَفَرَّقَا فِي بَعْضِ مَا هُنَالِكَ ثُمَّ إِذَا مُحَيِّصَةُ يَجِدُ عَبْدَ اللهِ بْنَ سَهْلٍ قَتِيلًا فَدَفَنَهُ ثُمَّ أَقْبَلَ إِلَى رَسُولِ اللهِ ﷺ هُوَ وَحُوَيِّصَةُ بْنُ مَسْعُودٍ وَعَبْدُ الرَّحْمَنِ بْنُ سَهْلٍ وَكَانَ أَصْغَرَ الْقَوْمِ فَذَهَبَ عَبْدُ الرَّحْمَنِ يَتَكَلَّمُ قَبْلَ صَاحِبَيْهِ فَقَالَ رَسُولُ اللهِ ﷺ «كَبِّرِ لِلْكُبَرِ فِي السِّنِّ فَصَمَتَ وَتَكَلَّمَ صَاحِبَاهُ ثُمَّ تَكَلَّمَ مَعَهُمَا» فَذَكَرُوا لِرَسُولِ اللهِ ﷺ مَقْتَلَ عَبْدِ اللهِ بْنِ سَهْلٍ فَقَالَ لَهُمْ «أَتَحْلِفُونَ خَمْسِينَ يَمِينًا وَتَسْتَحِقُّونَ صَاحِبَكُمْ أَوْ قَاتِلَكُمْ؟» قَالُوا «كَيْفَ نَحْلِفُ وَلَمْ نَشْهَدْ؟» قَالَ «فَتُبَرِّئُكُمْ يَهُودُ بِخَمْسِينَ يَمِينًا» قَالُوا «وَكَيْفَ تَقْبَلُ أَيْمَانَ قَوْمٍ كُفَّارٍ فَلَمَّا رَأَى ذَلِكَ رَسُولُ اللهِ ﷺ أَعْطَاهُ عَقْلَهُ»
