Should she give them a copy of her ID even though she wears niqaab?
Question

                I am studying public speaking and da’wah, and they have asked me for a copy of my national ID. I started to study and until now I have not given them the copy because I wear niqaab and I do not want the one who is in charge of collecting papers and the professor who teaches us to see my face. My question is: Is there any sin in handing it in?.
Praise be to Allah.
    If this study will benefit you and your society, and will 
    increase you in knowledge and help you to do good deeds and call people to 
    Islam, then we hope that there will be no sin in your giving those who are 
    in charge of the study a copy of your national ID. So long as they want a 
    copy of the ID and not the original, you can darken the picture with 
    something so that it will not show the features clearly. 

    We ask Allaah to guide you and make you steadfast. 

    And Allaah knows best.
