Menstruation during Hac is a common concern that Hz. Peygamber Muhammad (sallallahu aleyhi ve sellem) addressed directly and with compassion. When Aisha (may Allah be pleased with her) began menstruating during her hac ibadeti, she was distressed, and Hz. Peygamber reassured her by saying: 'This is something that Allah has decreed for the daughters of Adam. Do everything that the hacilar do, except do not perform Tavaf around the House until you are purified.' This foundational hadith establishes the principle that menstruation does not invalidate or prevent Hac — it only restricts Tavaf.
A menstruating woman may perform all rites of Hac without restriction except Tavaf around the Kabe, which requires ritual purity. She may: enter and remain in the state of ihram; stand at Arafat (the greatest pillar of Hac); proceed to Muzdelife; stay at Mina; throw pebbles at the Cemerat; have her hair cut; sacrifice an animal; make du'a; recite dhikr; and perform Say between Safa and Marwah (according to the majority view, Say does not require abdest). She should not enter the cami area of al-Mescid-i Haram during menstruation, though the open courtyard areas (mata'f) have been discussed by contemporary scholars for cases of necessity.
The farewell Tavaf (tavaf 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 Tavaf al-Ifadah — which is a pillar (rukn) of Hac 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 Tavaf 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.
