Salaam siki
Salam samia,
Indeed she is, she has to behave herself, otherwise , her men are suppose to take care of her.
And "he"? Doesn't "he" have to behave himself?
Is it your own opinion or you have supporting evidence? What happened to the verse 24:2? The existence of this verse is what makes me think in another way, not because I am a "woman"

.
Yes generally, but Nissa o kum simply means "Their women ", that could include all the women that a man is responsible for/takes care off.
If you scan the quraan, you will find this expression, when related to males,
always means "wives".
One incident of "Nissa i hinna" i can remember off hand , is 24-31. The women to relax their dress code, and "Nissa i hinna" is used , along with the rest of the list. I am sure these "Niss i hinna" are not their spouses. And there could be more if one makes a delibrate effort to search.
I am glad you brought this up! I once argued against this very expression being "women" and the person I was arguing against was very angry.
Here, apply another meaning of "nisaa': males she is their guardien, supporting them financially, therefore they are either too young (already mentioned) or with disabilities (plus of course parents, brothers, husband..who are all mentioned already).
If the husband is not an eye witness, and hence cannot testify under an oath, but he gets solid reports of certain incidents by 4 reliable witnesses , in the light of which he can suspect with a reasonable assurance , that her wife is most likely committing Fahishas, Then he may divorce her , and kick her immidiately out of the house.
Says who? <snetence in bold>
Please note that we have verse 4:19 which indicates just the opposite.
Also verse 24:7. Why can't he testify under an oath? Either he blieves them and is ready to testify under an oath, or he inclines towards not believing them. No one is forcing him to do anything. If he wants to divorce her he has to go to authorities and make the oath. Otherwise, no divorce on these premises.
As per she being locked up in the house for ever by the husband ? This is one of the worst options , i am quite sure that no women would like to be in those shoes
Being locked up is bad, and I think we are missing something in this verse. How can we lock up somebody for a crime when we have another verse giving us a different punishment (24:2), and another verse telling the spouse what to do in this case if the stated evidence is not available(24:7).
Quran does not advise honor killing, if someone does it , he/they are wrong.
You are missing my point. What I want to say is that fathers and brothers can go as far as killing, locking up is their "mercy".
