He was also asked—may Allah sanctify his soul—about a woman whose menstrual period began before the main circumambulation of Hajj (tawāf al-ifādah) and had not ended by the time the pilgrims departed, while she could not remain behind until it ended:

May she perform circumambulation in this condition out of necessity? If this is permissible, must she make a sacrificial offering? Is it recommended for her to take a ritual bath nonetheless?

If a woman knows from her usual menstrual cycle that her period will not end before the pilgrims depart, and she cannot remain behind, is Hajj still obligatory for her? If it is not obligatory, is it recommended for her to proceed and perform circumambulation? Give us a ruling; may you be rewarded.

He replied:

All praise is due to Allah. Scholars hold two well-known views on whether ritual purity is a condition for the validity of circumambulation.

The first is that it is a condition. This is the position of Mālik and al-Shāfiʿī, and one of the two positions reported from Ahmad.

The second is that it is not a condition. This is the position of Abū Hanīfah and the other position reported from Ahmad.
