"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
