Muhibullah, 20, a drug addict, is handcuffed in a cell in his 40-day incarceration at the Mia Ali Baba shrine in Jalalabad, Afghanistan, Thursday, May 1, 2014. It is believed locally that 40 days of chaining to a wall with a restricted diet at the 300-year old shrine can cure the mentally ill, drug addicts and those possessed by spirits. If a shrine keeper decides their situation is improving, they may be unchained for a few minutes. However, shrines such as Mia Ali Baba are frowned upon by health care professionals and other critics who say the remedy is ineffective and that those who run the incarceration prey on vulnerable people's religious beliefs and superstitions to make a profit.
