Maymun bin Mihran said: I came to Sayyidah Safiyyah bint Shaybah (may Allah be pleased with her), who was an elderly woman, and I asked her: "Did the Messenger of Allah (peace and blessings be upon him) marry while he was in the state of ihram?" She said: "No, he (peace and blessings be upon him) married her when both of them were out of ihram."
