From the perspective of Islamic law, if they tempted men to rape them, they are at fault, and must be punished. The rape must also have been public, since four male Muslim witnesses are required to have witnessed the act in order to establish it in Sharia court (cf. Qur’an 24:4, 24:14).
“ISIS extremists stone four women to death on charges of ‘committing adultery,’” by Sarbaz Yousef, Ara News, February 12, 2016 (thanks to The Religion of Peace):
ERBIL – The Islamic State (ISIS) has executed four women in the city of Mosul in Iraq’s northwestern Nineveh province, after accusing them of “committing adultery”, local sources reported on Thursday.
“The four victims were arrested earlier on wednesday [sic] in a raid by ISIS jihadis,” said Raafat Zarari, spokesman of the Nineveh media center.
“The jihadis claimed to have captured the women while committing adultery,” Zarari told ARA News in Mosul.
The ISIS-led Sharia Court issued a decision to publicly execute the four women, without mentioning any details about the men with whom the victims have supposedly committed adultery.
“The four women were stoned to death on Thursday in front of a large crowd of people in central Mosul,” Zarari reported.
Speaking to ARA News in Mosul, media activist Abdullah al-Malla said: “The four women were most likely exposed to sexual abuse at the hands of ISIS militants before being driven out of their homes and transferred to the Sharia Court.”
“The statement of the Sharia Court regarding the case of those four women has avoided mentioning the men who have been involved in the alleged adultery,” the source said. “Apparently, the victims have been raped by ISIS jihadis and then stoned to death on charges of committing adultery.”
