Ashtiani, 42, will be buried up to her chest, according to an Amnesty International report citing the Iranian penal code. The stones that will be hurled at her will be large enough to cause pain but not so large as to kill her immediately.
Ashtiani, who is from the northern city of Tabriz, was convicted of adultery in 2006.
She was forced to confess after being subjected to 99 lashes, human rights lawyer Mohammad Mostafaei said Thursday in a telephone interview from Tehran.
She later retracted that confession and has denied wrongdoing. Her conviction was based not on evidence but on the determination of three out of five judges, Mostafaei said. She has asked forgiveness from the court but the judges refused to grant clemency.
Amnesty International and other human rights activists are interceding on behalf of Sakineh Mohammadi Ashtiani. Again, CNN:
