Enslaving women is not what it used to be in the good old days of true jihad. People have become too selfish to do it properly.
Here is an Islamic authority explaining and defending the Muslim case for keeping women as sex slaves. The whole thing is worth reading if you can bear it.
This is how it ends:
One question that still remains is whether slavery still legally prevails anywhere in the Islamic world and whether it can be successfully implemented in this age. Well, there is no prevalence of lawful slavery in the Islamic world today and it would be difficult to implement it because of the stringent conditions attached to it. Firstly, the prisoners have to be captured in ‘Jihaad’ in the true sense of the word. Then again, If true ‘Jihaad’ did break out somewhere, there are still a number of other laws and conditions to abide by which are far too stringent for any Islamic country in the world to abide by in this time and age when people’s personal gains and whims and desire are being given preference to over Islamic Law. According to Islamic Law, captive female prisoners are also part and parcel of the booty. One fifth of the booty has to be first distributed to the needy, orphans, etc. The remaining four-fifths should then be distributed among the soldiers who participated in the war. The distribution can only take effect after the booty is brought into Islamic territory. The Ameerul-Mu’mineen (Head of the Islamic State) remains the guardian of the female prisoners until he allocates them to the soldiers. Only after a soldier has been allotted a slave girl, and made the owner of her, will she become his lawful possession. After she spends a period called ‘Istibraa’, which is the elapse of one menstrual period, it becomes permissible for her owner to have relations with her. After possession of the slave too there are a number of other laws that affect the master and slave. There is hardly any Islamic country today that can abide to all these conditions, with the result that it is quite difficult to implement slavery in this time and age.
Equally blood-chilling is this article from Civilus Defendus titled Four Stages of Islamic Conquest. One can mark just how far the conquest of various Western countries has progressed.
