“Earlier we saw Egyptian preacher Huwaini and Kuwaiti political activist Mutairi call for the reinstitution of sex-slavery. Before dismissing their position as aberrant, that is “radical,” for the record, here are respected Muslim scholar Majid Khadduri‘s thoughts on the matter:
The term spoil (ghanima) is applied specifically to property acquired by force from non-Muslims. It includes, however, not only property (movable and immovable) but also persons, whether in the capacity of asra (prisoners of war) or sabi (women and children). … If the slave were a woman, the master was permitted to have sexual connection with her as a concubine.
Still, some may seek to dismiss the notion of sex-slavery in Islam as theory, not actual practice, arguing that even if Sharia permits the sexual enslavement of infidel women, neither Egypt nor Kuwait formally permits it.”
