What is the ruling on the Hajj of a woman who experiences menstruation while at 'Arafah?

Question:
This is a question from Sister Maryam 'Abd al-Rahman from Riyadh. She says: During the standing at 'Arafah, her monthly period started. What are the remaining acts of Hajj that she is not permitted to perform herself? And if it had started before she arrived at 'Arafah, what is the ruling regarding her Hajj? Does she complete it, or does she cut it off? Or what does she do?

Answer:
Her Hajj is valid, and the fact that her monthly period started does not prevent the Hajj. Likewise, if she gave birth at 'Arafah, she completes her Hajj, even if she is in a state of post-natal bleeding; this does not cut off the Hajj. She remembers Allah with the Muslims at 'Arafah, she remembers Allah, she praises Him, she recites the talbiyah, and she raises her hands in supplication with the Muslims at 'Arafah, and at Muzdalifah. On the way, she recites the talbiyah and remembers Allah; this does not harm her. The Prophet (peace and blessings be upon him) said to 'A'ishah when she menstruated near her entry into Makkah before the Hajj, and she went to 'Arafah while menstruating, he said to her: So he ordered her to do what the pilgrims do, except for the tawaf while she is menstruating. May Allah be pleased with her.
Likewise, Asma' bint 'Umayyis, the wife of the Siddiq Abu Bakr (may Allah be pleased with them both), gave birth at the miqat, and the Prophet (peace and blessings be upon him) ordered her to enter the state of ihram as the people do, and to protect herself with a garment, and to do what the pilgrims do of remembrance, talbiyah, ihram, supplication, and other things, except for the tawaf. She is excused from prayer; she does not pray. This is a known matter, meaning: except for prayer and tawaf; because a menstruating woman does not pray, and a woman in post-natal bleeding does not pray. Likewise, she does not perform tawaf; because tawaf is of the same kind as prayer. Ibn 'Abbas said: "The tawaf of the House is prayer, except that Allah has permitted speech in it." So tawaf is of the same kind as prayer. Therefore, the menstruating woman and the woman in post-natal bleeding do not pray, but their Hajj is valid.
Likewise, if she menstruated before 'Arafah while on the way after entering ihram, she completes her Hajj with the people, but she does not perform tawaf. She stays in Makkah, remembers Allah, and sends blessings upon the Prophet (peace and blessings be upon him). The correct view is that she may also recite the Qur'an from memory. The correct of the scholars' opinions is that she may recite the Qur'an from memory, without the mushaf, in Makkah, in 'Arafah, and in every place. But she does not pray, and she does not perform tawaf until she becomes pure, as is known. So she remains in her ihram, and there is no harm in changing her clothes. If she changes her clothes, there is no harm. Every person in ihram may change clothes; the woman and the man alike, it does not harm. Changing clothes to other clothes, whether for an excuse or without an excuse.
The point is: that changing clothes does not harm, not from the side of the menstruating woman, nor from the side of the woman in post-natal bleeding, nor from the side of the other women in ihram, nor from the side of the men either. There is no harm in changing clothes. So she continues in her Hajj, she goes out with them to 'Arafah, and she stands in the station, and she remembers Allah, and she recites the talbiyah, and she supplicates to her Lord, and she raises her hands like the man. And likewise, she departs after sunset to Muzdalifah, and she stays in Muzdalifah until after the Fajr prayer. She stands with the people after Fajr, she supplicates to her Lord, she raises her hands, she recites the talbiyah on the way, and in Muzdalifah, but she does not pray, and she does not perform tawaf after that.
The point is: that she is like the pilgrims in their remembrance, their supplication, and the like, except for prayer and tawaf. And if she hastens with the people from Muzdalifah at the end of the night, there is no harm. If she hastens at the end of the night from Muzdalifah with the rest of the people, the Messenger (peace and blessings be upon him) granted a dispensation for the weak to hasten from Muzdalifah at the end of the night (peace and blessings be upon him). And if she hastens to Mina, she stays in Mina, and does not perform tawaf. She stays until she becomes pure. If she descends to Makkah, and does not become pure, she stays in Makkah until she becomes pure. When she becomes pure, she completes her Hajj: she performs tawaf, and she performs sa'y if she has sa'y upon her, and she completes her Hajj, and praise be to Allah. Yes.
