He said that ar-Rubaiyi‘, paternal aunt of Anas b. Malik, broke the front tooth of a girl of the Ansar, and when they went to the Prophet he ordered retaliation to be taken. Then Anas b. an-Nadr, paternal uncle of Anas b. Malik, said, “No, by God, her front tooth will not be broken, Messenger of God." He replied, “Anas, God’s decree is retaliation." But the people were agreeable to accepting a fine, so God’s Messenger said, “Among God’s servants there are those who, if one adjured God, would consent to it." (Bukhari and Muslim.)
