Sexual violence perpetrated by ISIL includes using rape as a weapon of war;[716] instituting forced marriages to its fighters;[717] and trading women and girls as sex slaves.[718]

There are many reports of sexual abuse and enslavement in ISIL-controlled areas of women and girls, predominantly from the minority Christian and Yazidi communities.[719][720] Fighters are told that they are free to have sex with or rape non-Muslim captive women.[721] Haleh Esfandiari from the Woodrow Wilson International Center for Scholars has highlighted the abuse of local women by ISIL militants after they have captured an area. "They usually take the older women to a makeshift slave market and try to sell them. The younger girls ... are raped or married off to fighters", she said, adding, "It's based on temporary marriages, and once these fighters have had sex with these young girls, they just pass them on to other fighters."[722]

The capture of Iraqi cities by the group in June 2014 was accompanied by an upsurge in crimes against women, including kidnap and rape.[723][724][725] According to Martin Williams in The Citizen, some hard-line Salafists apparently regard extramarital sex with multiple partners as a legitimate form of holy war and it is "difficult to reconcile this with a religion where some adherents insist that women must be covered from head to toe, with only a narrow slit for the eyes".[726]

As of August 2015, the trade in sex slaves appeared to remain restricted to Yazidi women and girls.[718] It has reportedly become a recruiting technique to attract men from conservative Muslim societies, where dating and casual sex are not allowed.[718] Nazand Begikhani said of the Yazidi victims, "These women have been treated like cattle ... They have been subjected to physical and sexual violence, including systematic rape and sex slavery. They've been exposed in markets in Mosul and in Raqqa, Syria, carrying price tags."[727] According to UN Reports the price list for IS sex slaves range from 40 to 160 US dollars. The younger the slave the more expensive. Girls and boys between the age 1–9 are referred to as the most expensive, with the cheapest being women between 40 and 50 years old.[728] According to another source the price of a slave equals the price of an AK-47.[729]

A United Nations report issued on 2 October 2014, based on 500 interviews with witnesses, said that ISIL took 450–500 women and girls to Iraq's Nineveh region in August, where "150 unmarried girls and women, predominantly from the Yazidi and Christian communities, were reportedly transported to Syria, either to be given to ISIL fighters as a reward or to be sold as sex slaves".[720] In mid-October, the UN confirmed that 5,000–7,000 Yazidi women and children had been abducted by ISIL and sold into slavery.[668][730] In November 2014 The New York Times reported on the accounts given by five who escaped ISIL of their captivity and abuse.[731] In December 2014, the Iraqi Ministry of Human Rights announced that ISIL had killed over 150 women and girls in Fallujah who refused to participate in sexual jihad.[732] Non-Muslim women have reportedly been married off to fighters against their will. ISIL claims the women provide the new converts and children necessary to spread ISIL's control.[733]

Shortly after the death of US hostage Kayla Mueller was confirmed on 10 February 2015,[734] several media outlets reported that the US intelligence community believed she may have been given as a wife to an ISIL fighter.[735][736][737] In August 2015 it was confirmed that she had been forced into marriage[738] to Abu Bakr al-Baghdadi, who raped her repeatedly.[739][738][740] The Mueller family was informed by the US Federal Bureau of Investigation (FBI) that Abu Bakr al-Baghdadi had sexually abused Ms. Mueller, and that Ms. Mueller had also been tortured.[740] Abu Sayyaf's widow, Umm Sayyaf, confirmed that it was her husband who had been Mueller's primary abuser.[741]

In its digital magazine Dabiq, ISIL explicitly claimed religious justification for enslaving Yazidi women.[742][743][744] According to The Wall Street Journal, ISIL appeals to apocalyptic beliefs and claims "justification by a Hadith that they interpret as portraying the revival of slavery as a precursor to the end of the world".[745] ISIL appeals to the hadith and Quran when claiming the right to enslave and rape captive non-Muslim women.[742][746][747] According to Dabiq, "enslaving the families of the kuffar and taking their women as concubines is a firmly established aspect of the Sharia's that if one were to deny or mock, he would be denying or mocking the verses of the Quran and the narration of the Prophet ... and thereby apostatizing from Islam." Captured Yazidi women and children are divided among the fighters who captured them, with one-fifth taken as a tax.[747][748] ISIL has received widespread criticism from Muslim scholars and others in the Muslim world for using part of the Quran to derive a ruling in isolation, rather than considering the entire Quran and hadith.[742][746][747] According to Mona Siddiqui, ISIL's "narrative may well be wrapped up in the familiar language of jihad and 'fighting in the cause of Allah', but it amounts to little more than destruction of anything and anyone who doesn't agree with them"; she describes ISIL as reflecting a "lethal mix of violence and sexual power" and a "deeply flawed view of manhood".[733] Dabiq describes "this large-scale enslavement" of non-Muslims as "probably the first since the abandonment of Shariah law".[747][748]

In late 2014, ISIL released a pamphlet that focused on the treatment of female slaves.[749][750] It claims that the Quran allows fighters to have sex with captives, including adolescent girls, and to beat slaves as discipline. The pamphlet's guidelines also allow fighters to trade slaves, including for sex, as long as they have not been impregnated by their owners.[749][750][751] Charlie Winter, a researcher at the counter-extremist think tank Quilliam, described the pamphlet as "abhorrent".[751][752] In response to this document Abbas Barzegar, a religion professor at Georgia State University, said Muslims around the world find ISIL's "alien interpretation of Islam grotesque and abhorrent".[753] Muslim leaders and scholars from around the world have rejected the validity of ISIL's claims, claiming that the reintroduction of slavery is un-Islamic, that they are required to protect "People of the Scripture" including Christians, Jews, Muslims and Yazidis, and that ISIL's fatwas are invalid due to their lack of religious authority and the fatwas' inconsistency with Islam.[450][448]

The Independent reported in 2015 that the usage of Yazidi sex slaves had created ongoing friction among fighters within ISIL. Sajad Jiyad, a Research Fellow and Associate Member at the Iraqi Institute for Economic Reform, told the newspaper that many ISIL supporters and fighters had been in denial about the trafficking of kidnapped Yazidi women until a Dabiq article justifying the practice was published.[754][755] The New York Times said in August 2015 that "[t]he systematic rape of women and girls from the Yazidi religious minority has become deeply enmeshed in the organization and the radical theology of the Islamic State in the year since the group announced it was reviving slavery as an institution."[718] The article claims that ISIL is not merely exonerating but sacralising rape, and illustrated this with the testimony of escapees. One 15-year-old victim said that, while she was being assaulted, her rapist "kept telling me this is ibadah"; a 12-year-old victim related how her assailant claimed that, "by raping me, he is drawing closer to God";[718] and one adult prisoner told how, when she challenged her captor about repeatedly raping a 12 year old, she was met with the retort, "No, she's not a little girl, she's a slave and she knows exactly how to have sex and having sex with her pleases God."[718]

In July 2016 it was reported by an AP investigation that ISIL was using mobile apps like Telegram to sell their sex slaves and identify the slaves of other ISIL members at checkpoints.[756] In 2016, the Commission for International Justice and Accountability said they had identified 34 senior ISIL members who were instrumental in the systematic sex slave trade and planned to prosecute them after the end of hostilities.[757]


Granted, ISIL is a bit more extreme than other forms of Islam. But their recruitment drive enticements, brutal treatment of women, rape, and slavery are rooted in islamic ideology of what is acceptable treatment of women as the spoils of war. "Firmly established by Sharia law and the Quran", in the "familiar language of jihad and 'fighting in the cause of Allah'". And they are widespread, way outside the realm of ISIS, in places such as Sudan and Nigeria.

And that's not even getting into the beheadings and other murders and atrocities cited outside of what I quoted.
Disgusting and brutal are words that only begin to express the inhumanity that is standard practice for these people.
