What is the ruling regarding a mother's oath that her brothers shall not walk in her funeral procession if she dies, and what is the ruling regarding her reconciliation with them without revoking the oath or offering expiation for it?

It is not permissible for a mother to swear to her brothers that they should not attend her funeral, because that entails cutting off kinship ties. She must expiate for her oath. Her brothers are not obligated to fulfill her oath if she dies, because it involves cutting off ties. Fulfilling an oath is obligatory if it involves performing an obligation or refraining from a sin. It is forbidden if it involves committing a sin or neglecting an obligation. It is recommended if it involves refraining from something disliked (makruh) or performing something recommended (mandub). If the woman does not expiate for her oath and dies, and her brothers attend her funeral, she is not considered to have broken her oath, and no expiation is due from her wealth.
