A man of the Ansar was killed at Khaybar and his relatives went to the Prophet ﷺ and mentioned that to him. He asked: Have you two witnesses who can testify to the murderer of your friend? They replied: Messenger of Allah! there was not a single Muslim present, but only Jews who sometimes have the audacity to do even greater crimes than this. He said: Then choose fifty of them and demand that they take an oath; but they refused and the Prophet ﷺ paid the blood-wit himself. (Using translation from Abū Dāʾūd 4524)   

أَصْبَحَ رَجُلٌ مِنَ الْأَنْصَارِ مَقْتُولًا بِخَيْبَرَ فَانْطَلَقَ أَوْلِيَاؤُهُ إِلَى النَّبِيِّ ﷺ فَذَكَرُوا ذَلِكَ لَهُ فَقَالَ أَلَكُمْ شَاهِدَانِ يَشْهَدَانِ عَلَى قَتْلِ صَاحِبِكُمْ؟ قَالُوا يَا رَسُولَ اللهِ لَمْ يَكُنْ ثَمَّ أَحَدٌ مِنَ الْمُسْلِمِينَ وَإِنَّمَا هُمْ يَهُوَدُ وَقَدْ يَجْتَرِئُونَ عَلَى أَعْظَمَ مِنْ هَذَا وَذَكَرَ الْحَدِيثَ  

[Machine] Our companions may be beaten and not die from it, so when they didn't say "kill him", they didn't pass judgment on him.  

أَصْحَابُنَا قَدْ يَكُونُ الضَّرْبُ وَلَا يَمُوتُ مِنْهُ فَلَمَّا لَمْ يَقُولَا قَتَلَهُ لَمْ يَحْكُمْ بِهِ
