If you have a Reddit account, you can try posting to /r/tipofmytongue. It's specifically for questions like this. :)

I don't know why, but it reminds me of this
Edit:
Summary taken from IMDB

"A woman and her physician husband rent an old mansion for the summer. They move into the upstairs nursery where the wife is confined as a type of therapy for her condition, a perceived nervous breakdown. A 1950's adaptation of a seminal work of feminist literature (written in 1892 by Charlotte Perkins Gilman), The Yellow Wallpaper."

It does sound like Not Without My Daughter

She wasn't Arabic (nor her husband btw, he was Persian) but yeah it's most likely Not Without My Daughter. Starring Sally Field. Your Mom probably remembered it like that because when the passport scene happens, they are in Iran and despite Field's character being American, she is wearing traditional Iranian garb for women.
