"Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) was asked what a husband should do if his wife refuses him when he asks for intimacy.*
It is not permissible for her to rebel against him or to withhold herself from him, rather if she refuses him and persists in doing so, he may hit her in a manner that does not cause injury, and she is not entitled to spending or a share of his time [in the case of plural marriage].” Majmoo’ al-Fataawa, 32/279"
If the women doesn't consent and the husband says ok I'm not feeding you anymore because you are disobedient to me, and then she says ok do what you have to, does that mean this is not rape anymore? Did the man really get the woman's consent?
There you go and I do hope when people are quoting the prophet (pbuh) they give some sort of reference at least, otherwise it becomes hearsay. Don't approach like a beast? Where's your proof and bring the Hadith reference.
My only point was why do we have to degrade our mothers and sisters to the level of a slave just to justify Islam to the Kuffar.
The bigger issue isn't sex with a slave girl, that is a given, a man in whose right hand he possess a female slave is bound to do something sometime even if it is for curiosity. If there is an issue here it is slavery. Also there is a clear verse in the Quran saying that one can have sex with a slave even if she is married. And the slave has no right to resist unless the owner decided she has a valid reason.
