Menstruation during Haji is a common concern that Nabi Muhammad (shallallahu alaihi wa sallam) addressed directly and with compassion. When Aisha (may Allah be pleased with her) began menstruating during her ibadah haji, she was distressed, and Nabi reassured her by saying: 'This is something that Allah has decreed for the daughters of Adam. Do everything that the jamaah haji do, except do not perform Tawaf around the House until you are purified.' This foundational hadith establishes the principle that menstruation does not invalidate or prevent Haji — it only restricts Tawaf.
A menstruating woman may perform all rites of Haji without restriction except Tawaf around the Kabah, which requires ritual purity. She may: enter and remain in the state of ihram; stand at Arafah (the greatest pillar of Haji); proceed to Muzdalifah; stay at Mina; throw pebbles at the Jamarat; have her hair cut; sacrifice an animal; make du'a; recite dhikr; and perform sa'i between Safa and Marwah (according to the majority view, sa'i does not require wudhu). She should not enter the masjid area of al-Masjidil Haram during menstruation, though the open courtyard areas (mata'f) have been discussed by contemporary scholars for cases of necessity.
The farewell Tawaf (tawaf al-wada) is waived entirely for menstruating women, based on the explicit hadith of Ibn Abbas. This is agreed upon by all four schools and represents a genuine concession (rukhsah). As for Tawaf al-Ifadah — which is a pillar (rukun) of Haji and cannot be waived — the woman should ideally wait until she is purified to perform it. If she cannot wait (for example, her travel group is departing and she cannot stay), the Hanafi school permits her to perform Tawaf al-Ifadah in a state of menstruation, with a dam (sacrifice) as penalty. Other schools require her to wait, and some contemporary scholars have extended the Hanafi concession for genuine hardship cases.
