Sayyidah Aishah (may Allah be pleased with her) said: Safiyyah bint Huyayy (may Allah be pleased with her) began menstruating at Mina during the Farewell Hajj, after performing the tawaf al-ifadah. I said: O Messenger of Allah (peace and blessings be upon him)! Safiyyah has begun menstruating. The Prophet (peace and blessings be upon him) said: "Is she going to hold us back?" I said: She has performed the tawaf al-ifadah. The Prophet (peace and blessings be upon him) said: "Let her depart."
