Praise be to Allah.Praise be to Allaah.
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.
