She is not allowed to wear hijab, so how can she go out to work and meet her needs?
Question

                My question is about hijab. Women here are forbidden to wear hijab and they are treated badly in addition to the fact that they are not allowed to enter their workplaces or other places such as police stations, so they have no choice but to take off their hijab. What is the solution, especially since we have to meet our own needs and especially at work?.
Praise be to Allah.For a woman to wear hijab 
    in front of non-mahram men is an obligation that is indicated in the Qur’aan 
    and Sunnah and by scholarly consensus. It is not permissible for anyone to 
    enjoin otherwise or to prevent those who want to follow this command, 
    otherwise he is going against the command and laws of Allaah. Allaah says 
    (interpretation of the meaning): 
“It is not for a 
    believer, man or woman, when Allaah and His Messenger have decreed a matter 
    that they should have any option in their decision. And whoever disobeys 
    Allaah and His Messenger, he has indeed strayed into a plain error”
[al-Ahzaab 33:36] 
“And whoever contradicts 
    and opposes the Messenger (Muhammad صلى الله 
    عليه وسلم) after the right path has been shown clearly to him, and 
    follows other than the believers’ way, We shall keep him in the path he has 
    chosen, and burn him in Hell — what an evil destination!”
[al-Nisa’ 4:115] 
“But 
    no, by your Lord, they can have no 
    Faith, until they make you (O Muhammad
    صلى الله عليه وسلم) judge in all 
    disputes between them, and find 
    in themselves no resistance against your decisions, and accept (them) with 
    full submission”
[al-Nisa’ 4:65]
Secondly: 
It is not permissible for a 
    woman to be careless about this obligation or to go out of her house with 
    any part of her body uncovered, unless she is forced to do so in a case of 
    necessity that makes that which is haraam permissible, such as if she is 
    summoned to a police-station, and she cannot avoid going there because that 
    would result in harm to herself or her property.  
As for going out to work, 
    if she does not have to do that because what she is given by her husband or 
    father or other relative who is obliged to support her is sufficient for 
    her, then it is not permissible for her to go out to work if that will 
    result in her taking off her hijab. 
The Muslims have to 
    cooperate with regard to this matter and ensure that Muslim women are 
    independent of means so that they are not compelled to go out in ways that 
    involve sin. That may be achieved by calling on fathers and relatives to 
    spend generously on them and to provide some useful work that women can do 
    in their homes, so that they will have no need to go out for any reason that 
    may lead to them taking off their hijab and exposing them to harm because of 
    wearing it.  
This depends on convincing 
    the men that hijaab is obligatory, because many of them do not care about 
    that, and some of them are keen for their wives and daughters to go out and 
    work, and some of them will not agree to marry a woman who does not work, 
    even if her work means that she has to take off the hijaab. This ignorance 
    and shortcoming on the part of the men is one of the greatest causes of this 
    problem, and one of the reasons why the matter is not being resolved. We 
    should strive to spread this knowledge, remind people of it and train them 
    to follow it, so that every man will be keen to protect his family and 
    dependents, and will realize that he will be questioned tomorrow about this 
    trust – did he take care of it or not? The Prophet  (peace and blessings 
    of Allaah be upon him) said: “There is no person to whom Allaah entrusts the 
    care of others and he does not take care of them sincerely, but he will not 
    even smell the fragrance of Paradise.” Narrated by al-Bukhaari (7150) and 
    Muslim (142). 
In fact, Muslims are 
    individually obliged to strive to remove this evil, and to adopt all the 
    necessary means of achieving that, through organizations and associations 
    etc., so as to relieve their women of hardship and enable every Muslim woman 
    to wear her hijab. They should not despair and give up on doing this duty. 
    How many rights have been restored to people by means of patience, effort 
    and striving.  
Thirdly: 
If a woman is in dire 
    straits and cannot find any alternative to going out to work because she has 
    no one to support her, and she is also forced to take off the hijab, then if 
    she is able to migrate to a land where she will be able to practise her 
    religion openly and obey the commands of her Lord, she is obliged to do so. 
     
Ibn al-‘Arabi said in 
    Ahkaam al-Qur’aan (1/612): 
Migration (hijrah) from dar 
    al-kufr (kaafir lands) to dar al-Islam (Muslim lands) is obligatory.  
And from a land where 
    innovation is widespread. Imam Maalik (may Allaah have mercy on him) said: 
    It is not permissible for anyone to settle in a land in which the salaf are 
    reviled. 
And from a land in which 
    haraam things are prevalent, for seeking halaal is an obligation for every 
    Muslim. 
But not everyone may be 
    able to migrate, and it cannot be regarded as a solution for all Muslim 
    women. 
If a women really needs to 
    go out of her house to work or do some errands  etc, and the matter is 
    limited to uncovering the face only, then we hope that there is nothing 
    wrong with her doing that. 
But we must strive to solve 
    this problem completely, as stated above, by advising those who are in 
    positions of responsibility and asking them for this religious and personal 
    right. The daa’iyahs who call people to Allaah and the scholars have to 
    explain to the people that hijab is an obligation that Allaah has enjoined 
    upon the Muslim women. 
It is very strange that we 
    see this intense war against hijab, the symbol of chastity and purity, and 
    at the same time we see that the door is wide open for immoral and 
    promiscuous women.  
Be patient, O believing 
    women, for the reward of Allaah is precious and there will come a day in 
    which the religion of Allaah will prevail over all other religions. 
“It is He Who has sent 
    His Messenger (Muhammad صلى الله عليه وسلم) 
    with guidance and the religion of truth (Islam), to make it superior over 
    all religions even though the Mushrikoon (polytheists, pagans, idolaters, 
    disbelievers in the Oneness of Allaah) hate (it)”
[al-Tawbah 9:33]
“And Allaah has full 
    power and control over His Affairs, but most of men know not” [Yoosuf 12:21
We ask Allaah to guide this 
    ummah so that people of obedience will be honoured and people of 
    disobedience will be humiliated, , and to help you and all the Muslim women 
    to adhere to hijab and give up wanton display and unveiling. 
And Allaah knows best.
