According to the Islamic doctrine, every woman is inferior to or lower in status than a man. Every Kafir (non-Muslim) woman is lower in status than an Islamic woman, and she can be made a slave by capture in jihad.
A Kafir woman can be used as a sex-slave and raped as this is morally acceptable according to the Sharia law of Political Islam. Mohammed himself had Kafir female captives whom he used as sex-slaves:
Koran 4:34 Allah has made men superior to women because men spend their wealth to support them. Therefore, virtuous women are obedient, and they are to guard their unseen parts as Allah has guarded them. As for women whom you fear will rebel, admonish them first, and then send them to a separate bed, and then beat them. But if they are obedient after that, then do nothing further; surely Allah is exalted and great!
Koran 33:59 Messenger! Command your wives and daughters and the wives of the believers to not let their veils fall down. Therefore, they will be recognized and not be assaulted. Allah is forgiving and merciful!
Koran 2:223 Your women are your plowed fields: go into your fields when you like, but do some good deed beforehand and fear Allah. Keep in mind that you will meet Him. Give good news to the believers.
Koran 33:50 Messenger! We allow you your wives whose dowries you have paid, and the slave-girls Allah has granted you as spoils of war, and the daughters of your paternal and maternal uncles and aunts who fled with you to Medina, and any believing woman who gives herself to the Messenger, if the Messenger wishes to marry her. This is a privilege for you only, not for any other believer. We know what We have commanded the believers concerning wives and slave-girls. We give you this privilege so you will be free from blame. Allah is forgiving and merciful!
Koran 23:1-11 The successful ones will be the believers who are humble in their prayers who avoid vain conversation, who contribute to the needy, and who abstain from sex (except with their wives or slaves [slaves are bought or taken in battle], in which case they are free from blame, but those who exceed these limits are sinners). Those who honor their promises and contracts and who pay strict attention to their prayers will inherit Paradise. They will dwell there forever.
Islam devotes a great deal of attention to how women are to be treated. The Islamic Doctrine of Women reveals the principles for this treatment and how it is antithetical to the idea of human equality.
