is an Arab-Islamic term, that means, roughly I think, isolation.
The term seems to play some role in the story posted by Saudi Jeans:
So few days ago in Dammam some members of the religious police somehow got the impression that they could storm a women’s public restroom on the courniche to arrest someone. They went in and moments later emerged dragging a girl who was crying, screaming and begging them to leave her alone. She tried to run away but fell on the ground. The Haya’a men apparently thought it was okay to hit and kick her, so they did that in the street while people were watching, then they carried her and threw her in the back of their jeep. [...]
UPDATE 23/12/09: According to al-Watan daily, the girl has been released. The newspaper quoted security sources who said the girl was arrested based on the suspicion of a khulwa, while the boy who allegedly was with her managed to escape. The haya’a in the EP declined to comment on the case. The police said they received the case and they are searching for the boy..
As I googled for the meaning of 'khulwa" I found this story:
A young man and woman in Saudi Arabia decided to do the ultimate act of evil: to take a drive together in the man's Toyota Camry.
Of course, a man and woman being alone together - even in a car - is known as "khulwa" as can be punished with many lashes and a prison sentence.
Our heroes at the Commission for the Promotion of Virtue and the Prevention of Vice got tipped off about this flagrant violation of human decency and started to go after the criminals. [...]
On the Madina-Tabuk Road, in the Tabuk area, the chase ended when the Camry rammed head-on into a truck and burst into flames.
The man’s body was totally charred. The woman’s body was ripped into two by the force of the impact. They were too disfigured for immediate identification.
But most importantly, our heroes managed to stop a flagrant act of khulwa, and, especially, any unspeakable acts that might have followed.
And this story:
The sentencing of a 75-year-old Arab widow to 40 lashes and four months in prison for mingling with two young men, who were reportedly bringing her bread, has sparked fresh criticism of the Kingdom’s judiciary and the Commission for the Promotion of Virtue and Prevention of Vice.
Khamisa Sawadi, a Syrian who was married to a Saudi, was convicted and sentenced last week for meeting men who were not her immediate relatives. The two men, including one who was Sawadi’s late husband’s nephew, were also found guilty and sentenced to prison and lashes.
