Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada , states:
If a woman starts menstruating before or while traveling for hajj, she is required to assume ihram from the miqat like everyone else, after having washed and cleaned herself, regardless of whether she is still menstruating or not. This is what the Prophet (peace and blessings be upon him) advised his own wives and the women who were traveling for hajj. He told them to do all of the rites of hajj except tawaf. As for tawaf, she should do it after she is free from menses, and after she has performed ghusl.
In summary, a menstruating woman should assume ihram from the miqat like everyone else; make talbiyah, and engage in dhikr and supplications; she may also recite the Quran from her memory, and select verses and du’as of the Qur’an, although she may not recite the Qur’an from the Mushaf unless there is a need to do so.”
