She did Hajj wearing niqaab - what should she do?


Last year, I did the Omra and the Haj.I knew that wearing niqab was forbidden, but Ithought that Ihad to wear it because there were a lot of people.During the Haj, someone told me that what I did was wrong and that I had to veil my face with something else. What have I to do to correct this mistake?.
