How does a menstruating woman perform her Umrah if she begins menstruating before or after entering into Ihram, and she is with a group that cannot wait for her, and she cannot return to Makkah?

If a woman experiences menstruation before assuming ihram and passes the miqat, she must assume ihram. When she arrives in Mecca, she should wait until she becomes pure. If it is not possible for her to wait and she wishes to travel, she should perform ghusl and complete her umrah. This is permissible according to some scholars. However, it is more cautious (i.e., al-ahwat) to offer a sheep as a hady.
