Also, when the verse of hijab, Khimar came, all muslim women started observing it. Those who did not have an extra piece of cloth, tore open any cloth they found to make themselves an outer covering to cover themselves up. They did not have the guts to outrightly defend their right not to cover, they respected the message of Islam so much that whether or not they initially agreed with it, they knew it was in their best interest to follow it.
Among them , were women who were Munafiqs( who claim to be muslims, yet shy away from following any islamic practice) and there were women who were newly reverted to Islam, none of them took it as a choice to be acted upon later when THEY thought it was convenient. They all followed the Commandment from Allah as is. Apparently it seems that some women of today are more confident in denying that it is the will of Allah, and associate choice of matters Inside of religion , when all matters have been chosen by Allah for them ALREADY, how then the matter of choice arises? I don't understand.
Choice is that you follow Islam or you don't, or you say yes this is true and I InshAllah hope to follow it instead of totally twisting the essence of the message to their own desires. I have a friend who does not cover herself like muslims should, but she always says that yes i know women should cover, she is just finding it hard being stuck in a family where no one does it and being less covered is a fashion statement, and she has unfortunately been subjected to some unpleasant instances where she wishes so bad that she had covered up properly.
Ofcorse, she will have to practice some will power for herself rather than living all her life according to the wishes of the family/ friends. Once you submit to Allah, you are free from the unnecessary pressures of the society. But this I say for a woman who is already born a Muslim and has read that commandment of Allah, it is totally understandable however, if a new person has approached Islam and does not know much about it and wants to take things at their pace. I wouldn't call hijab a criteria of judgment of character of a woman,neither does Islam say that, but it is a muslim woman's identity that one embraces when they follow it.
I dont agree with the punishment part though, I think such matters have been told to be settled within the home, apart from your brothers, fathers and husbands, i don't think strange people can tell you to cover, its not going to work either anyway. And the matter of telling should be very sweet and very humble at first instead of a strict severe tone. One should discuss its merits and any confusions ( if any) or the fears of the women who hesitate from doing it. After that i don't think you can do much to make anybody cover, unless ofcorse they are dressing up immorally.
And only Allah knows best.
