Should women wear overcoat or jilbab to cover themselves (for tasattur)?
As far as we know, the name or picture of is worn is not important in Islam. The important one is its function. The function is whether dresses cover the whole body or not.
If a dress is like that, namely, the scarf covers the whole hair on head, the overcoat covers the contours of the body fully, the thick socks cover all skin, and the necessary covering will do its function whatever you call it.
This way of dressing is the result of Fatwa. It is obligatory.
Furthermore if you also wear jilbab over this way of dressing, of course it is the result of Taqwa, it is highly appreciated. It is to hide oneself completely.
It is not possible to force everybody to wear jilbab, because Taqwa is optional but fatwa is obligatory. Those who want or are interested in can prefer to wear it and those who do not want to wear it should not be insisted, because forcing oneself to wear according to Taqwa could cause not getting dressed according to Fatwa; some other negative results could also happen. Everybody can be interested in the way of wearing according to Fatwa; if we show the way of dressing according to Taqwa for those who cannot get dressed according to Fatwa, they will have difficulty and they can lose interest.
It means that a wide headscarf, an overcoat or a topcoat that is wide and long enough to conceal the contours of the body, a thick pair of socks, a pair of shoes whose heel part is closed, will be enough for the way of covering according to Fatwa. Almost everybody can adopt and wear it. In addition to this, wearing jilbab is a high virtue because it is the result of Taqwa. However, it should not be as a result of insistence; it should be a result of preference and love. Striving for the best can sometimes prevent from performing the good one. At that point, a person can regret saying “I wish I would do just the good one firstly, the best later”
Furthermore, today we need to make people love the way of Islamic dressing. Not everybody can wear jilbab, which is the summit of covering oneself. However, a beautiful overcoat or an elegant topcoat, a wide and an elegant headscarf, and a thick pair of socks attract almost every woman’s interest. Those who wear in this way will not be exposed to the pressure of the environment and covet those who see it. So, it would be a favorable way of Islamic dressing and it would prevent an unfavorable way. Those who have kismet to get dressed like that will see they are happy and at ease. After they find ease to get dressed according to Fatwa, they can think of getting dressed according to Taqwa. Then we would talk about advancement.
It is a reality that there are many hesitant people who do not know how and like whom they will live. To be a model for them, to seem in a way that they will like, and to make them feel that they can perform the Islamic rules is a very important service and virtuous guidance. Namely, a woman with the Islamic way of dressing is a preacher and guide for those hesitant people. With their elegant way of dressing, they are a model, warning and advice for them. Those who have kismet will wear and be interested in this reasonable way of dressing. The whole duty is in the hands of our women with the Islamic way of dressing. They should be in a clean and an elegant way, far away from showing that kind of dressing bad and ugly.
This criterion from the Hadith of the Messenger of Allah is very good warning and guidance for our covered women:
“Women who get dressed properly and cause it spread will take its price. Those who do not get dressed properly and made it spread will take its penalty." It means that we should get dressed properly and take its price; and we should get away from getting dressed improperly.
