Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her) said: We set out with the intention of Hajj. When we reached the place of Sarif, I began menstruating and started crying out of distress. During this, the Messenger of Allah (peace and blessings be upon him) came and asked, "What has happened to you? Have you started menstruating?" I said, "Yes." He said: "This is a thing which Allah has ordained for the daughters of Adam. So you should also perform all the rites of Hajj, except do not perform the Tawaf of the House (Ka'bah)." Sayyidah Aisha (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) offered a cow as a sacrifice on behalf of his wives.
