Is the 'umrah of one who has cut off ties with his brother, verbally and physically abused him and his family, and continues to do so despite his brother's attempts at reconciliation, accepted?

The acceptance of Umrah is in the hands of Allah, and it is achieved through sincerity and conformity with the Sunnah. The existence of problems between the two brothers does not prevent its acceptance. It is advisable to strive to counsel the two brothers and reconcile between them, as Allah Almighty said: "No good is there in much of their private conversation, except for whoever enjoins charity or معروف (that which is good and righteous) or reconciliation between people." (An-Nisa: 114) It is also advisable to encourage the wronged brother to repel his brother's ill treatment with kindness and patience, as Allah Almighty said: "Repel evil with that which is better." (Fussilat: 34) It is also encouraged to maintain the morning and evening adhkar (remembrances) for protection.
