In Islam, Kafir women taken as slaves in jihad were raped with Mohammed’s approval. Koran: 4:24 "And all married women (are forbidden unto you) save those whom your right hands (sword hand) possess.”
According to Islamic doctrine, rape & sex slavery is not a sin. Rape of the Kafir is permitted by Mohammed and Allah in the Koran, enshrined in Sharia law. Under Sharia, Kafir women can be raped and there is no penalty. Islam is the only political system in the world that includes rules for rape and war. Rape is a tactic of jihad.
Apologists like to argue that Koran 4:24 only applies to times of war. In Islam, the natural state between Islam and Kafir world is war, dar al harb, not peace. Peace, dar al Islam, comes only after Sharia is implemented and there is 100% submission.
More Islamic reasons condoning rape--Islam divides the world into two camps: 1) the believers in Allah and Mohammed his prophet, who are the best of all people and 2) their enemies, the rest of humanity, or Kafirs. Islam is so concerned with Kafirs (non-Muslims) that the Koran describes in detail their treatment. Kafir is considered the lowliest of all beings, filthy, defiled and hated by Allah. They can be deceived, robbed, beat, raped, and murdered by Muslims.
There are constant ongoing rapes by Muslims against Kafirs around the world. This is another example of the continuous 1400 year history of jihad. These crimes are political statements with ramifications for all other cultures, especially Western civilization. The most disturbing aspect of the Islamic rapes of Kafirs is not the act itself, but the Kafir dhimmi response of cowardly submission by ignoring those rapes.
