Ar-Rabi, the daughter of An-Nadr broke the tooth of a girl, and the relatives of Ar-Rabi` requested thegirl's relatives to accept the Irsh (compensation for wounds etc.) and forgive (the offender), but theyrefused. So, they went to the Prophet (ﷺ) who ordered them to bring about retaliation. Anas bin An-Nadrasked, "O Allah"; Apostle! Will the tooth of Ar-Rabi` be broken? No, by Him Who has sent you withthe Truth, her tooth will not be broken." The Prophet (ﷺ) said, "O Anas! Allah"; law ordains retaliation."Later the relatives of the girl agreed and forgave her. The Prophet (ﷺ) said, "There are some of Allah'sslaves who, if they take an oath by Allah, are responded to by Allah i.e. their oath is fulfilled). Anasadded, "The people agreed and accepted the Irsh."
