I fought in Jaish-al-Usra (Ghazwa of Tabuk) along with the Prophet (ﷺ) and in my opinion that was the
best of my deeds. Then I had an employee, who quarrel led with someone and one of the them bit and
cut the other's finger and caused his own tooth to fall out. He then went to the Prophet (with a
complaint) but the Prophet (ﷺ) canceled the suit and said to the complainant, "Did you expect him to let
his finger in your mouth so that you might snap and cut it (as does a stallion camel)?"
Narrated Ibn Juraij from `Abdullah bin Abu Mulaika from his grandfather a similar story: A man bit
the hand of another man and caused his own tooth to fall out, but Abu Bakr judged that he had no
right for compensation (for the broken tooth).
