33:50 - "Prophet, We have made lawful to you the wives to whom you have granted dowries and the slave girls whom God has given you as booty."
Muslim men were allowed to have sex anytime with females slaves - Sura 4:3, 4:29, 33:49.
Slaves are as helpless before their masters as idols are before God - Sura 16:77
You call secularism perverted. I think Islam is the most sexually open religion. You can have 4 wives, unlimited number of concubines and then you have sex slaves who cannot even refuse to have sex with you.
If you claim Quran is a book for all people and of all times... Why do you criticize ISIS for using Yazidi girls as sex slaves and buying and selling human beings?
