What is the ruling on a girl remaining in her adoptive parents' home after finding out about her adoption, and what is the ruling on her going for Umrah without a mahram, and what should she do to avoid Allah's wrath, knowing that she was not breastfed by them, has no other place, and does not know her real family?

Adoption is forbidden and void. The adopted girl is not attributed to the family; rather, she is attributed to her real father if he is known. Otherwise, she is given a general attribution (such as "daughter of Allah's servant"). The man, his brothers, and his wife's brothers are non-mahram (definition) to her. It is permissible for her to live with them as long as there is no seclusion or unlawful mixing or display of adornment. It is permissible for her to travel for 'Umrah (definition) or Hajj al-Islam with trustworthy company if she does not have a mahram, and she should be promptly married off so she can travel with her husband.
