Maymun bin Mihran (may Allah have mercy on him) said: I asked Safiyyah bint Shaybah (may Allah have mercy on her): Did the Messenger of Allah (peace and blessings be upon him) marry Maymunah (may Allah be pleased with her) while in the state of ihram? She said: No, rather he married her while not in ihram.
