"I went on a campaign with the Messenger of Allah in the Army of Hardship, and this was the deed of which I was most sure. I had a hired man who fought with another person. One of them bit the finger of the other, who pulled his finger away and a front tooth fell out. He went to the Prophet who considered the tooth to be in vain, and said: "Would he put his hand in your mouth for you to bite it?"
غَزَوْتُ مَعَ رَسُولِ اللَّهِ ﷺ جَيْشَ الْعُسْرَةِ وَكَانَ أَوْثَقَ عَمَلٍ لِي فِي نَفْسِي وَكَانَ لِي أَجِيرٌ فَقَاتَلَ إِنْسَانًا فَعَضَّ أَحَدُهُمَا أُصْبَعَ صَاحِبِهِ فَانْتَزَعَ إِصْبَعَهُ فَأَنْدَرَ ثَنِيَّتَهُ فَسَقَطَتْ فَانْطَلَقَ إِلَى النَّبِيِّ ﷺ فَأَهْدَرَ ثَنِيَّتَهُ وَقَالَ أَفَيَدَعُ يَدَهُ فِي فِيكَ تَقْضَمُهَا
