Wife Discipline In Islam (One of the top misconceptions in Islam)

Allah, the Exalted, stated in the Glorious Qur'an:
(... As to those women on whose part you see ill-conduct, admonish them (first), (next,) refuse to share their beds, (and last,) beat them (lightly, if it is useful). But if they return to obedience, seek not against them means (of annoyance). Surely, Allah is Most High, Most Great.) [Al Quran 4:34]
Islam forbids beating women and warns strictly against it. The Prophet (Peace be upon Him) never beat any of his wives or servants, as his wife Aishah (may Allah exalt their mention) reported in an authentic tradition (Bukhari #2328). Women are, in general, weaker than men in their physique and stamina. Women are often unable to defend themselves against violence. Although beating of women is generally forbidden, Islam permits the beating of wives in a restricted and limited sense only as a final solution and acceptable valid reason when all else fails. This is analogous to spanking children when all else fails and they must learn a lesson in obedience for their own protection and success.
In the verse we quoted, Allah deals with the case of a wife who behaves immorally towards her husband's rights. The treatment of this extremely sensitive issue comes in gradual stages, as we have noticed from the verse. Medicine, or treatment of any ailment, can be very bitter at times. But an ill person will take the remedy gladly and bear the bitterness of the medicine in order to be cured from his illness. The remedy to treat a wife blameworthy of immoral behavior, as we have noticed, comes in three gradual stages:
First stage: The stage of advice, counseling and warning against Allah's punishment. A husband must remind his wife of the importance of protecting his rights in Islam. This stage is a very kind and easy one. But, if this treatment does not work and proves to be ineffective, then the husband may resort to the next stage.
Second stage: To leave the wife's bed. Or, if one sleeps in the same bed with her, he will turn his back to her, not touch her, talk to her or have intercourse with her. This stage, as noticed, combines both strictness and kindness, although it is a very harsh practice on both. But, if this treatment does not work, then the husband may resort to the final stage of discipline explained below.
Third and final stage: Beating without hurting, breaking a bone, leaving black or blue marks on the body, and avoiding hitting the face or especially sensitive places at any cost. The purpose of beating her is only to discipline and never retaliation or with desire to hurt by any means. Islam forbids severe beating as punishment.
The Prophet (Peace be upon Him) said:
"None of you should beat his wife like a slave-beating and then have intercourse with her at the end of the day".
