What is the ruling on one who performed the tawaf for 'Umrah without ritual purity, being ignorant?

Question:
A girl came with her parents for 'Umrah, and during the tawaf around the Ka'bah, her wudu' was broken, and she continued the tawaf without ritual purity, and she completed the 'Umrah and exited the state of ihram. What is the ruling on that? Knowing that she had only reached puberty a short time ago, and she was ignorant of the rulings, and did not know that ritual purity is obligatory in the tawaf, and she is still in Makkah.

Answer:
This [means] her 'Umrah is invalid; her tawaf, sa'y, and shortening of the hair have no value. Her 'Umrah is invalid, and she remains in her state of ihram, so she has to come to the House and perform the tawaf for the 'Umrah, walk between al-Safa and al-Marwah, and shorten her hair, because the 'Umrah remains upon her. Even if she is young, if a young person enters ihram, it is obligatory for him to perform the rites, whether he is young or an adult.
