"Men are overseers over women, by reason of that wherewith Allah hath made one of them excel over another, and by reason of that which they expend of their substance. Wherefore righteous women are obedient, and are watchers in husbands absence by the aid and protection of Allah. And those wives whose refractoriness ye fear, exhort them, and avoid them in beds, and beat them; but if they obey you, seek not a way against them; verily Allah is ever Lofty, Grand." - Quran 4:34 (read more)

"Narrated 'Abdullah bin 'Umar : The Jew brought to the Prophet a man and a woman from amongst them who have committed (adultery) illegal sexual intercourse.

"With regard to wife beating... In a nutshell, it appeared as part of a program to reform the wife. [According to the Koran], first 'admonish them,' [then] 'sleep in separate beds, and beat them.'... This method appeared as part of the treatment of a rebellious wife... By Allah, even if only one woman out of a million can be reformed by light beatings... It's not really beating, it's more like punching... It's like shoving or poking her. That's what it is." - Dr. Ahmad Al-Tayyeb
