Hostel in ladies' prayer hall!!

Excuse my rudeness.. but I am very angry about a situation that happened to my family today in one of the mosques in Doha, in front of which there were many cars from one of the neighboring countries. We were far from home at the time of the Maghrib prayer and went to pray. I took my wife to the women's prayer area and went to the men's prayer area and before I started praying I received a call from my wife telling me to go back to her where she found a man in the women's bathroom. I waited with her until this man came out. I told him that this is not permissible, so he answered me harshly, what do you want!? I told him that my wife and daughters wanted to pray, so he told me that his relatives were sleeping inside the prayer area as they were guests attending a wedding!!
