What is the ruling for a woman who intends to perform 'Umrah or Hajj, but her menstrual period begins at the miqat?

Question:
May Allah reward you. Many questions have been received asking about the ruling for a woman when her menstrual period comes to her while she is at the miqat, or during the tawaf, or after the tawaf and before the sa'y. What does she do in all these situations? And what is the ruling if she forgets to shorten her hair when exiting the state of ihram, and her husband comes to her before that?

Answer:
This question contains many questions. First, if her menstruation comes to her at the miqat and she intends to perform 'Umrah or Hajj, she enters the state of ihram while menstruating, and there is no harm in that. Ihram does not require ritual purity. She enters ihram while menstruating. The Prophet (peace and blessings be upon him) ordered Asma bint 'Umayy (may Allah be pleased with her) when she gave birth and had post-natal bleeding to enter ihram. He ordered her to enter ihram with the people. Ihram does not require ritual purity. But when she reaches Makkah, she does not perform tawaf or sa'y until the blood stops. She performs the full ritual bath, then performs tawaf and sa'y. His saying (peace and blessings be upon him) . This is his question.
The second question: if she menstruates while she is performing tawaf. She entered ihram in a state of purity and arrived in Makkah while pure, then menstruation occurred during the tawaf. Her tawaf is invalid. She exits the tawaf area and exits the Sacred Mosque. She goes to her lodging and her place of residence and waits until the blood stops. Then she performs the full ritual bath, performs tawaf and sa'y, and completes her 'Umrah.
The third question: if she performed tawaf while pure, then the blood came down after she finished the tawaf. There is no blame on her. She performs sa'y. Sa'y does not require ritual purity. She performs sa'y while menstruating, and her sa'y is valid. It is only the tawaf that is not valid with menstruation. As for sa'y, there is no harm. She performs sa'y, shortens her hair, and completes her 'Umrah. There is no harm.
The fourth question: a woman performed tawaf and sa'y and forgot to shorten her hair, and her husband had intercourse with her. She still has the obligation to shorten her hair. It is obligatory for her to shorten her hair. She does not complete her 'Umrah except by shortening her hair. The intercourse that occurred requires a fidyah (ransom payment) from her. She pays the fidyah by slaughtering a sheep in Makkah and distributing it to the poor of the Haram.
