I cannot imagine my husband physically "disciplining" me in any way, shape, or form. In fact, the thought makes me chuckle. When he has an issue with me, he talks to me, we work it out, done.
Not a single finger is raised in my house, not even against the dog.
Neither in our house. But Islam do not give rulings to general situations only but also to specfic cases such as the time before the the prophet sallalahu 'alayhi wassalam were women were herited and belliteled and women were dealed with like animals or objects not as humans.
Also, these specific cases are not only specfic to that time, even these days some men have no control over their temper if he sees someone trying to take over his land, you know in arabic there this saying that jalousy between men over a women cannot be settled until theres blood and death while women's jaleousy most of the times do not depass the limit of throwing words or breaking stuffs. (Its just the meaning, the saying is not like that lol), but the point is not the jealousy between men but to show that men fight for their lands, and a family is not a fighting area therefore Islam understood that some men may be so rebellious when they see their women trying to take the governor place by force that it may lead to beating, and here Islam put rules and bidings and limits that a men cannot depass.
See how many wifes are being harmed and beaten every day in the western world ( I know you may disagree on this term, but you know what I mean), and when they are drunk and come back home theres no limit at all. Therefore Islam forbids alcohol, first step, order men to advise rebellious women and be patient and reward them for that , second step, and if at any time the men cannot control his anger ( as I said, specific cases) he is ordered to not to harm or to let any spots on his wife body , third step. Now tell me, when you beat someone , is it possible not to let blue marks on his/her body? No, until you are beating kindly or calmly or anything else.
Sharia's first job is not to give cure, but to put safety tips before the worst happen then come the cure or the judgment.
And as I advised Mr Paul, you could try to revise the principles of Islam concerning the family in Islamic society and the huge place it takes in Shariah, then Inshallah you can understand all the specific stuffs easily
