Quran 4:34:
Men are in charge of women by [right of] what Allah has given one over the other and what they spend [for maintenance] from their wealth. So righteous women are devoutly obedient, guarding in [the husband's] absence what Allah would have them guard. But those [wives] from whom you fear arrogance - [first] advise them; [then if they persist], forsake them in bed; and [finally], strike them. But if they obey You [once more], seek no means against them. Indeed, Allah is ever Exalted and Grand.

But if they once again become faithful Pieces of property like a good Muslim would be for their man then all good ans seek no further means against them. Because Allah is so understanding and has laid out such a straightforward and precise process for managing your sex slave, I mean wife, this makes makes him superior and great. Yuppers.
