Oaths
2 hadiths
Verily, if one of you insists on fulfilling an oath by which he may harm his family that is more sinful in the sight of Allah, the Almighty, than breaking the oath and paying the (oath-breaking) expiation that Allah imposed
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: “Verily, if one of you insists on fulfilling an oath by which he may harm his family that is more sinful in the sight of Allah, the Almighty, than breaking the oath and paying the (oath-breaking) expiation that Allah imposed.”
Among Allah's slaves, there are some who, if they take an oath by Allah (concerning something), Allah fulfills it
Anas reported that his aunt, Ar-Rubayyi‘, broke the incisor of a girl. The aunt's family requested the girl's relatives for pardon, but they refused, then they proposed a compensation, but they refused. Then they went to the Messenger of Allah (may Allah's peace and blessings be upon him) and refused everything except retribution. So the Messenger of Allah (may Allah's peace and blessings be upon him) judged that retribution be applied. Anas ibn An-Nadr said: "O Messenger of Allah, will the incisor of Ar-Rubayyi‘ be broken? No, by the One Who sent you with the Truth, her incisor will not be broken." Therefore, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "O Anas, the prescribed law of Allah is retribution." Thereupon, those people agreed on pardon. Then the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Among Allah's slaves, there are some who, if they take an oath by Allah (concerning something), Allah fulfills it."
