What are the consequences for a woman who completed her 'Umrah while menstruating, without informing her family, and then went on to complete the rituals of 'Umrah? And what expiation is due upon her years after her Hajj and 'itikaf, without having made up for that incomplete 'Umrah?

A menstruating woman is not permitted to enter the Grand Mosque or perform circumambulation (Tawaf) around the Kaaba. If a woman performs Tawaf while menstruating, her Tawaf is invalid, her Umrah is incomplete, and she remains in the state of Ihram until she completes her Umrah. If she subsequently performs a second Umrah, her Tawaf, Sa'i, and shortening of hair will count towards the first Umrah, and it will suffice for it. However, if she does not perform another Umrah, but then performs Hajj as a Mutamatti' (one who performs Umrah and Hajj in the same journey), the Umrah performed with the Tamattu' will suffice for her first Umrah. If she performs Hajj as a Mufrid (one who performs Hajj only), she becomes a Qarin (one who combines Umrah and Hajj in the same Ihram) and is liable for a compensatory sacrifice (dam) for combining them. There is no blame upon her for the transgressions she committed before the completion of the first Umrah due to her ignorance of the ruling.
