I am a young man working in Makkah, and my family is in Jeddah. I used to stay in Makkah from Saturday till Wednesday, and on Thursday and Friday I would go to my family in Jeddah. One week I went to Jeddah, and found that my father had changed the design of the room where I sleep; he had blocked the door through which I used to enter the room and had opened a door in the opposite wall, and he had changed the furniture in the room. Praise be to Allah, I used to offer most of my prayers in the mosque, but sometimes I missed the prayers (in the mosque), so I offered them in my room. One month after these changes have been made in the room, I found out that I had been praying in a direction opposite to the qiblah. What is the ruling on that? A reminder: I only go there on Thursday and Friday, and I offer most of my prayers in the mosque.
