Praise be to Allaah.

Firstly: 

In Islam there are rules and guidelines concerning a woman working. A woman cannot work in a place where Allaah is disobeyed or in a place where there is mixing with men. Her work should be for a necessary or urgent purpose, because she has a great mission and important work to do in her house, raising her children and serving her husband, and guarding his house and his wealth, and no one can take her place in these roles no matter how much the arrogant deny her role and fabricate lies about it. They just want women to go out, although they know the importance of what she does in her home.  

The scholars of the Standing Committee said: 

It is not permissible for a woman to work in a place where there is mixing with men. What she must do is observe proper shar’i hijab and avoid places where men gather, and she should look for permissible work that does not involve any of these things that Allaah has forbidden. If a person gives up something for the sake of Allaah, Allaah will compensate him with something better than it. Allaah says (interpretation of the meaning):

“And whosoever fears Allaah and keeps his duty to Him, He will make a way for him to get out (from every difficulty).

3. And He will provide him from (sources) he never could imagine. And whosoever puts his trust in Allaah, then He will suffice him. Verily, Allaah will accomplish his purpose. Indeed Allaah has set a measure for all things”

[al-Talaaq 65:2-3] 

Shaykh ‘Abd al-‘Azeez ibn Baaz, Shaykh ‘Abd al-‘Azeez Aal al-Shaykh, Shaykh Saalih al-Fawzaan, Shaykh Bakr ibn Abu Zayd 

Fataawa al-Lajnah al-Daa’imah (17/231) 

We have quoted the evidence for the prohibition on mixing in the answer to question no. 1200. We have discussed the ruling on mixed workplaces in the answer to question no. 39178. You will find the guidelines on women’s work in the answer to question no. 22397. In the answer to question no. 6666 there is important advice to do with women working in mixed environments.  

Secondly: 

We do not think that this kind of job is permissible even if those who are asking for refugee status are genuine, because the basic principle is that it is haraam to settle in kaafir lands. If we add to that the fact that they seeking help by lying in order to achieve that, this reinforces the prohibition and it is not permissible for anyone to help them in that. We know that there are cases of necessity for some people who need to resort to settling in that country, and special rulings apply to them as cases of necessity, but we are talking about work that deals with all of them and does not differentiate between cases of necessity and others. 

In many questions we have discussed the issue of settling in kaafir lands and the evils that result from that, and the conditions which must be met by the one who settles there for a legitimate shar’i reason which makes it permissible for him to settle there. Please see the answers to question no. 11793, 14235 and 27211. 

Thirdly: 

Lying is a blameworthy characteristic according to the laws of Allaah, and it is contrary to faith, as Abu Bakr al-Siddeeq (may Allaah be pleased with him) said. Helping these false refugees is cooperating in sin and transgression, which is haraam according to the laws of Allaah. Allaah says (interpretation of the meaning):  

“Help you one another in Al‑Birr and At‑Taqwa (virtue, righteousness and piety); but do not help one another in sin and transgression. And fear Allaah. Verily, Allaah is Severe in punishment”

[al-Maa’idah 5:2] 

al-Haafiz Ibn Katheer (may Allaah have mercy on him) said: 

Allaah enjoins His believing slaves to cooperate in doing good, which is righteousness, and in avoiding evil, which is piety, and He forbids them to support one another in falsehood or to cooperate in sin and haraam things. 

Tafseer Ibn Katheer (2/12, 13). 

See the fatwa of the Scholars of the Standing Committee forbidding helping in writing for one who tells lies and bears false witness, in the answer to question no. 35573. 

Thirdly: 

It is good that you have given up this work. As for the money that you earned from it, if you did not know that your work was haraam, or if someone issued you a fatwa stating that it was permissible, then your taking it was permissible for you, so long as you give up the work immediately. This is what has happened in your case, and you can make use of that money. But you should repent sincerely for what has happened, and do a lot of righteous deeds, especially charity.

We ask Allaah to accept your righteous deeds and to increase you in guidance and righteousness. 

And Allaah knows best.
