It is narrated from Hazrat Anas (may Allah be pleased with him) that Rubayyi‘, who was the paternal aunt of Hazrat Anas (may Allah be pleased with him), broke the tooth of a girl. Then her family asked the girl's family for forgiveness, but they refused to forgive and came to the Prophet (peace and blessings be upon him) demanding retribution (qisas). Anas bin Nadr (may Allah be pleased with him) said, "O Messenger of Allah (peace and blessings be upon him)! Will the tooth of so-and-so (my sister) be broken?" The Prophet (peace and blessings be upon him) said, "Anas! The decision of the Book of Allah is retribution (qisas)." He said, "By Him Who has sent you with the truth, the tooth of so-and-so woman will not be broken." In the meantime, those people became pleased and forgave her and gave up their demand for retribution. Upon this, the Prophet (peace and blessings be upon him) said, "There are some servants of Allah, if they swear by Allah about something, Allah surely fulfills their oath."
