What is the ruling on a woman performing 'Umrah while she is menstruating?

Question : The questioner says: A woman came to perform 'Umrah, and before starting the tawaf she began menstruating. She remained silent about it to her family out of modesty, and she proceeded with her 'Umrah until she finished it. What is required of her?

Answer : She must now know that she remains in her state of ihram. This woman who menstruated and was too shy to tell her family, and who performed tawaf and sa'y with them, we tell her that she is currently in ihram, and it is obligatory for her to avoid what a person in ihram must avoid. When she becomes pure from menstruation, she must perform tawaf and sa'y and shorten her hair, because her first tawaf was invalid, and the sa'y based on it was invalid because it was based on an invalid tawaf, and likewise the shortening of hair, because it must be done after the tawaf and sa'y.
