A number of online services are charging "divorced" Muslim women thousands of pounds to take part in "halala" Islamic marriages, a BBC investigation has found. Women pay to marry, have sex with and then divorce a stranger, so they can get back with their first husbands.
Farah - not her real name - met her husband after being introduced to him by a family friend when she was in her 20s. They had children together soon afterwards but then, Farah says, the abuse began.
"The first time he was abusive was over money," she tells the BBC's Asian Network and Victoria Derbyshire programme.
