Aishah (may Allah be pleased with her) said: Safiyyah (may Allah be pleased with her) had begun menstruating after the ifadah. I told the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) said: "Is she going to hold us back?" I said: O Messenger of Allah (peace and blessings be upon him)! She has performed the ifadah, and after that she began menstruating. He (peace and blessings be upon him) said: "Then let her depart."
