Assalamualaikum Warahmatullahi Wabarakatuh
As a girl and well, a hijabi, I always hear girls say "at least she wears hijab" "she's making an effort" "at least she covers her hair" AT LEAST, AT LEAST, AT LEAST ! Don't you get tired of always having to say to yourself, at least I'm wearing it, right ?
Hijab, isn't just about covering your hair and wearing long pants or even wearing long sleeved shirts. Hijab is about being modest inside and out. That's where we all miss out on. For example (this maybe sensitive but like Rasulullah said, if an advice is given and it is a good advice, accept it), some girls they wear the hijab with long pants & long sleeved shirts but it's always never right. Like maybe the hijab doesn't cover her bosoms and back properly or her long pants are so tight that you can see the shape of her legs or the long sleeved shirt she's wearing is not up to her wrist.
It was mentioned in the Quran about the hijab in Surah An-Nur : ayah 31
which meant, "And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed." (Sahih International)
and also in Surah Al-'Ahzab : ayah 59
"O Prophet, tell your wives and your daughters and the women of the believers to bring down over themselves [part] of their outer garments. That is more suitable that they will be known and not be abused. And ever is Allah Forgiving and Merciful." (Sahih International)
The Quran specifically said to "wrap their headcovers over their chests" which means you have to wear your hijab correctly with covering your chest not wearing it but exposing your chest. It was also mentioned in the Quran that you cover your aurah to avoid physical desire but do you really think the fellow men can lower down their gaze if you walk around with hijab but with your chest exposed and pants so tight that it exposes the shape of your body ? Think about it. Men are responsible for their own gaze but you, ukhti are responsible for what you give them to gaze at.
