The name Islam means submission and so the conquest (war) is never ending until the planet is submitted to Allah ( Quran 24:55 ). So Islam is effectively at war until the whole world belongs to Islam. This primary directive has resulted in 57 countries now being overrun and 8 islamic insurgencies in non Muslim countries trying to add to that number today.
So the seizure and rape of non-Muslim girls/women as spoils of war and their use as sex slaves is sanctioned in the Qur’an. This is why such high numbers of rape cases exist with comparatively low Muslim numbers in western nations.
According to Islamic law, Muslim men can take “captives of the right hand” (Qur’an 4:3, 4:24, 33:50). The Qur’an says: “O Prophet! We have made lawful unto thee thy wives unto whom thou hast paid their dowries and those whom thy right-hand possesseth (slaves) of those whom Allah hath given thee as spoils of war” (33:50). 4:3 and 4:24 extend this privilege to Muslim men in general.
