Are the deeds of one who quarreled with her sisters until they died accepted, and is there repentance and expiation for her?

Islamic law prohibits abandonment, and this prohibition is particularly emphasized regarding relatives, especially siblings. The Prophet, peace and blessings be upon him, said: "Do not hate each other, do not envy each other, do not turn away from each other, and be, O servants of Allah, brothers. It is not permissible for a Muslim to abandon his brother for more than three nights." Among the negative consequences of abandonment is the withholding of forgiveness on Mondays and Thursdays until the disputing parties reconcile. The Prophet, peace and blessings be upon him, said: "The gates of Paradise are opened on Monday and Thursday, and every servant who does not associate anything with Allah is forgiven, except for a man between whom and his brother there is animosity. It is said: 'Wait for these two until they reconcile.'" It is obligatory to strive for reconciliation between the sister and her brothers and to urge her to repent. However, there is no evidence that abandonment prevents the acceptance of good deeds.
