Lady Aisha Siddiqa (may Allah be pleased with her) narrates: She said, "O Messenger of Allah (peace and blessings be upon him)! I think we will have to stay because of Lady Safiyyah (may Allah be pleased with her)." The Prophet (peace and blessings be upon him) asked, "What has happened to her?" Lady Aisha (may Allah be pleased with her) replied, "She has started menstruating." The Prophet (peace and blessings be upon him) said, "Has she performed the Tawaf al-Ifadah?" I said, "Yes, but she has started menstruating." The Prophet (peace and blessings be upon him) said, "Then it is not necessary for her to stay; she may depart."
