It was narrated that Anas said:"Eighty men from 'Ukl came to the Messenger of Allah [SAW]" and he (the narrator) mentioned a similar report up to the words: "And he did not have (their wounds) cauterized." And he said: "They killed the herdsman."
أَخْبَرَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، قَالَ حَدَّثَنَا الأَوْزَاعِيُّ، قَالَ حَدَّثَنِي يَحْيَى بْنُ أَبِي كَثِيرٍ، قَالَ حَدَّثَنِي أَبُو قِلاَبَةَ، عَنْ أَنَسٍ، قَالَ قَدِمَ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم ثَمَانِيَةُ نَفَرٍ مِنْ عُكْلٍ فَذَكَرَ نَحْوَهُ إِلَى قَوْلِهِ لَمْ يَحْسِمْهُمْ وَقَالَ قَتَلُوا الرَّاعِيَ .
