It is narrated from Hazrat Aisha (may Allah be pleased with her) that after the Tawaf al-Ziyarah, Hazrat Safiyyah (may Allah be pleased with her) began her menstrual period. This was mentioned to the Prophet (peace and blessings be upon him), so the Prophet (peace and blessings be upon him) said, "Will this prevent us?" I said, "She began her period after the Tawaf al-Ziyarah." So the Prophet (peace and blessings be upon him) gave the order to depart.
