What is the ruling regarding a father's displeasure with his daughter, knowing that she did not disobey him, and that he was the one who wronged her and expelled her from the home?

If your father has wronged you without a legitimate Shar'i (Islamic legal) excuse, then he has erred. You must still honor him, treat him with kindness, pray for his guidance and righteousness, and seek the help of virtuous and close individuals to speak with him. His displeasure with you will not harm you if it is not due to any shortcoming on your part, and you must exert effort to please him. It is not permissible for a father to prevent his child from maintaining ties of kinship (silat al-rahim), and obedience to him in this matter is not obligatory.
