its not a stupid question.u see if a guy does that n woman protests(say u r in pak for instance)n demands divorce so many Chamchas of the guy will jump in telling the lady ok that happened in state of anger n Hes ur husband he can do it in islam its ok for a husband he won't b answerable to Allah for that so y make n issue n just go back to ur house. n then there was a lady(MIL)who would say haan mard ko ghussa dilayo tu aisa tu hota he hai.is main kia bari baat hai n then she would quote this hadees where a Sahabi used to keep a long stick to scare his wife n keep her in control.When i asked the authenticity of hadees the answer was"I read it somewhere dunno where" Now for everyones info it not adultery based hitting/fight we r talking abt.
elaborate on that plzz Sounds interesting.
