The majority of scholars from all four schools agree that ritual purity is a condition for the validity of Tavaf, just as it is for namaz. Therefore, a menstruating woman should not perform Tavaf until her menstruation ends and she performs gusul. This is based on Hz. Peygamber's instruction to Aisha when she began menstruating during Hac: 'Do everything the haci does, except do not perform Tavaf around the House until you are pure.' She was instructed to continue with all other rites of Hac but to delay her Tavaf.
Sheikh Ibn Baz stated that a menstruating woman must wait until she becomes pure and then perform gusul before doing Tavaf. If she is performing Hac, she can do the standing at Arafat, stay at Muzdelife, stone the Cemerat, and perform all other rites except Tavaf, which she delays until she is pure. He emphasized that there is no time limit for Tavaf al-Ifadah, so she should not rush or compromise her purity.
Sheikh Ibn Uthaymeen mentioned that in cases of extreme necessity — such as when a woman's travel group must leave and she cannot stay behind — some scholars from the Hanbali school permitted Tavaf with menstruation as a concession, citing the principle that conditions are waived when impossible to fulfill. However, this is a minority view, and the stronger position according to the majority is that she must wait. Modern travel arrangements generally allow women to delay their departure, reducing the need for this concession.
