Will God hold me accountable for my feelings towards my father who is shunning and mistreating me, and for my brother shunning me, knowing that my father is a Hafiz of the Quran and an Imam of a mosque, but he does not act upon what he memorizes and mistreats me? And will my Umrah be accepted while my father is shunning me?

The husband must treat his wife well. The father's cursing of his daughter's mother contradicts this and he does not have the right to prevent his daughter from maintaining ties with her mother. The daughter must strive to maintain ties with her mother discreetly to avoid angering her father, for the father's mistreatment does not negate the duty to honor him. The daughter must spend on her poor father. Repentance and seeking the father's forgiveness are obligatory if she has fallen short in her duty towards him. Umrah (definition) is not affected by the father's boycott, and the daughter must pray to Allah to mend the situation during Umrah. One must be wary of thinking ill of others without proof.
