Anas bin Malik reported,

Rabi, his paternal aunt, broke the front tooth of a young girl. Her family was asked to pardon the offense, but they refused. They were then offered compensation, but they refused that as well. They came to the Messenger of Allah ﷺ insisting on nothing but retaliation, so the Messenger of Allah ﷺ ordered that retaliation be carried out.Anas bin Nadr said, "Messenger of Allah, will Rabi's tooth really be broken? No, by the One who sent you with the truth, her tooth will not be broken."The Messenger of Allah ﷺ replied, "Anas, the Book of Allah prescribes retaliation."The girl's family then accepted and pardoned the offense.The Messenger of Allah ﷺ said, "Among the servants of Allah are those who, if they swear an oath by Allah, He fulfills it for them."

عن أنس

أن الربيع عمته كسرت ثنية جارية فطلبوا إليها العفو فأبوا فعرضوا الأرش فأبوا فأتوا رسول الله ﷺ وأبوا إلا القصاص فأمر رسول الله ﷺ بالقصاص فقال أنس بن النضر يا رسول الله أتكسر ثنية الربيع لا والذي بعثك بالحق لا تكسر ثنيتها فقال رسول الله ﷺ يا أنس كتاب الله القصاص فرضي القوم فعفوا فقال رسول الله ﷺ إن من عباد الله من لو أقسم على الله لأبره
