Ashraf Kolhari, a 37-year-old mother of four has been held in Tehrans notorious Evin prison for five years, Amnesty said in a statement on Thursday.
On or around July 2006, she received the order for the implementation of her sentence, and is reportedly due to be executed by stoning by the end of July, the rights group said.
Kolhari had an extra-marital affair after her divorce request was rejected by the court, reportedly on the basis that she had children, and therefore had to resume living with her husband, the statement said.
She was sentenced on two charges; the first was for participating in the murder of her husband, for which she received a sentence of 15 years imprisonment; the second was for adultery as a married woman, for which she was sentenced to execution by stoning. Article 83 of the Iranian Penal Code stipulates that the penance for adultery by a married woman with an adult man is execution by stoning, it said.
