وَعَنْ يَعْلَى بْنِ أُمَيَّةَ قَالَ: غَزَوْتُ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ جَيْشَ الْعُسْرَةِ وَكَانَ لِي أَجِيرٌ فقاتلَ إِنساناً فعض أَحدهمَا الْآخَرِ فَانْتَزَعَ الْمَعْضُوضُ يَدَهُ مِنْ فِي الْعَاضِّ فَأَنْدَرَ ثَنِيَّتَهُ فَسَقَطَتْ فَانْطَلَقَ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأَهْدَرَ ثَنِيَّتَهُ وَقَالَ: «أَيَدَعُ يَدَهُ فِي فِيكَ تَقْضِمُهَا كَالْفَحْلِ»
Ya'la ibn Umayyah reported: I went on the Expedition of Hardship with the Messenger of God. I had a hired worker who fought with another man. One bit the other, and the one who was bitten pulled his hand from the biter’s mouth, knocking out one of his front teeth. He went to the Prophet, who ruled that no retaliation was due for his tooth. He said: ‘Would he leave his hand in your mouth for you to chew it like a stallion?’
Translation notes
The English witness adds a footnote identifying the expedition as Tabuk; this is not in the Arabic passage.
