I've seen people declaring alcohol and other crimes halal, I think same situation might be in this case.
If there's no verse about dealing with a disobedient husband what does this mean?
It means either the wife can do the same to him or may be even more so.
Of course when we are unaware and ignorant of what Quran and hadith state about domestic violence then whatever interpretation the wife beater gives us we'd listen and shut up and thus won't be able to argue.
Here now you have done the same thing which you accused others of doing. Interpretion of quran as suited. Well atleast they have some verse to go by whereas you are shooting arrows in the drak.
You can twist and turn it however you like but fact remain the same; quran **permits **husbands to strike their disobedient wives as a last resort.
