Original post by daisychain_Its not a "beating".
Quran is very clear on this issue. Almighty Allah says: "Men are the protectors and maintainers of women, because Allah has given the one more strength than the other, and because they support them from their means. Therefore, the righteous women are devoutly obedient and guard in the husband's absence what Allah would have them to guard. As to those women on whose part you fear disloyalty and ill-conduct, admonish them (first), (next), refuse to share their beds, (and last) beat them (lightly); but if they return to obedience, seek not against them means (of annoyance); for Allah is most High and Great (above you all). If you fear a breach between them twain, appoint (two) arbiters, one from his family and the other from hers. If they wish for peace, Allah will cause their reconciliation; for Allah has full knowledge and is acquainted with all things." (Quran: An-Nisaa 34-35)
It is important to read the section fully. One should not take part of the verse and use it to justify one's own misconduct. This verse neither permits violence nor condones it. It guides us to ways to handle delicate family situation with care and wisdom. The word "beating" is used in the verse, but it does not mean "physical abuse". The Prophet (p.b.u.h.) explained it "dharban ghayra mubarrih" which means "a light tap that leaves no mark". He further said that face must be avoided. Some other scholars are of the view that it is no more than a light touch by siwak, or toothbrush.
Generally, the Prophet (p.b.u.h.) used to discourage his followers from taking even this measure. He never hit any female, and he used to say that the best of men are those who do not hit their wives. In one Hadith he expressed his extreme repulsion from this behavior and said, "How does anyone of you beat his wife as he beats the stallion camel and then embrace (sleep with) her?” (Al-Bukhari, English Translation, vol. 8, Hadith 68, pp. 42-43)
It is also important to note that even this "light strike" mentioned in the verse is not to be used to correct some minor problem, but it is permissible to resort to only in a situation of some serious moral misconduct when admonishing the wife fails, and avoiding from sleeping with her would not help. If this disciplinary action can correct a situation and save the marriage, then one should use it."
