Narrated from Ummul Momineen Aisha (may Allah be pleased with her) that she said to the Messenger of Allah (peace and blessings be upon him): "O Messenger of Allah! Safiyyah bint Huyayy has started menstruating." The Messenger of Allah (peace and blessings be upon him) said: "Perhaps she will detain us? Did she not perform Tawaf with you all?" The people said: "Yes, she did." So he (peace and blessings be upon him) said: "Then (there is no harm), let us proceed."
