Assalamu Alaikum Wa Rahmatullah
If a woman completes umrah comes to room and has started haidh before cutting hair, what should she do?
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of ALLAH the Most Gracious, the Most Merciful.
Assalamualaikum Wa Rahmatullahi Wa Barakaatuh
If she experienced your haidh while making the Tawaaf of Umrah, and completed even one circuit in that state, then sacrificing an animal is wajib on her. This sacrifice will rectify the error and the Umrah will be considered valid and complete. However, if she experienced haidh while making Sai’ or afterwards then there is no sacrifice due upon her.
This sacrifice is the slaughtering of a goat, a sheep, a one-seventh part of a cow, or a one-seventh part of a camel within the precincts of the Haram.
However, if she was not aware of when her bleeding started then her haidH will be considered to start from the moment she saw the blood. If she first came to know of the blood when she arrived back at the hotel room after having completed Tawaf and Sai’ then her Umran will be complete.
Only Allah Ta’ala knows best.
