I listened to this disturbing article yesterday.
Excerpt: But while IS’s embrace of outright slavery has been singled out for censure, religious and political leaders have been more circumspect about other “slave-like” conditions prevalent across the region. IS’s targeting of an entire sect for kidnapping, killing and sex trafficking, and its bragging, are exceptional; forced labour for sexual and other forms of exploitation is not . . . Scholars are sharply divided over how much cultural mores are to blame. Apologists say that, in a concession to the age, the Prophet Muhammad tolerated slavery, but—according to a prominent American theologian trained in Salifi seminaries, Yasir Qadhi—he did so grudgingly and advocated abolition . . .Other scholars insist, however, that IS’s treatment of Yazidis adheres to Islamic tradition.
