Why do Muslim scum treat women like farm animals? It's in their disgusting holy book: Quran 4:34.

Quran (4:34) - "Men are the maintainers of women because Allah has made some of them to excel others and because they spend out of their property; the good women are therefore obedient, guarding the unseen as Allah has guarded; and (as to) those on whose part you fear desertion, admonish them, and leave them alone in the sleeping-places and beat them; then if they obey you, do not seek a way against them; surely Allah is High, Great."

Wife-Beating

Does Islam allow a man to hit his wife? 

Yes, but only if she doesn't do as he asks. The beating must stop if the woman complies with her husband's demands. Behind verbal abuse and abandonment, beating is intended as last resort solution to coerce submission.

According her testimony in the Hadith, Muhammad physically struck his favorite wife for leaving the house without his permission. It is not known how he treated his less-favored wives.
