"Permitted to you, on the night of the fasts, is the approach to your wives. They are your garments and ye are their garments. Allah knoweth what ye used to do secretly among yourselves; but He turned to you and forgave you; so now associate with them, and seek what Allah Hath ordained for you, and eat and drink, until the white thread of dawn appear to you distinct from its black thread; then complete your fast Till the night appears; but do not associate with your wives while ye are in retreat in the mosques. Those are Limits (set by) Allah: Approach not nigh thereto. Thus doth Allah make clear His Signs to men: that they may learn self-restraint." - Quran 2:187 (read more)

"We must know that [wife] beating is a punishment in Islamic religious law,....No one should deny this because this was permitted by the Creator of Man, and because when you purchase an electric appliance or a car you get instructions – a catalogue, explaining how to use it. The Creator of Man has sent down this book [the Quran] in order to show man which ways he must choose....We shouldn't be ashamed before the nations of the world who are still in their days of ignorance, to admit that these [beatings] are part of our religious law..." - Muslim cleric on Qatar TV
