Can I eat with my wife in my room even though my father wants us to eat with him in the dining room?

All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

It is permissible for you to eat with your wife in your room even if your father wants you to eat with him in his room. However, it is better to fulfill your father's wish and eat with him if you do not have an excuse not to do so. Verily, the father has a great right over his children, and showing dutifulness towards him is one of the greatest good deeds to draw closer to Allaah. Abu Ad-Dardaa' narrated that the Prophet, sallallaahu ‘alayhi wa sallam, said, "The parent is the middle gate to Paradise. So if you wish, lose that gate, or preserve it." [Ibn Maajah and At-Tirmithi]

Allaah knows best.
