The menstruating woman is not allowed to do tawaf and she should remain in Makkah until she becomes pure; if she leaves, then she must come back and do tawaf. Ibn Taymiyyah views that if a woman gets her menses and cannot remain in Makkah or come back to it if she leaves before doing tawaf, then either she may have an injection to stop the bleeding, and then do tawaf; or she may put on a sanitary pad to prevent the blood contaminating the mosque, and do tawaf, as this is a case of necessity.
