The obligation of a woman who performs Hajj while menstruating

The questioner: A woman performed Hajj on behalf of someone else. On the ninth day, the Day of 'Arafah, she began menstruating and had not yet reached her guardian. She performed all the rituals of Hajj while menstruating, including the tawaf. Then she performed the farewell tawaf while still menstruating. When she arrived home, she did not inform her guardian, and four years have passed, even though she is a widow. What is the ruling on this Hajj?
The ruling is that her Hajj is not complete, and the tawaf al-ifadhah remains upon her now; because it is a pillar, and Hajj is not complete without it. So she must now go to Makkah, enter the state of ihram for 'Umrah, perform tawaf, perform sa'y, and shorten her hair for the 'Umrah. Then she must perform the tawaf for the previous Hajj. Otherwise, she remains in the state of her remaining ihram and is sinful regarding the agency she accepted; because she has not completed it to this day, and it is a liability upon her conscience. So she should go to Makkah immediately before Ramadan,Meaning: from today if possible, and her guardian should go with her.
