Sayyiduna Abu Rafi' (may Allah be pleased with him) said: "The Messenger of Allah (peace and blessings be upon him) married Sayyidah Maymunah (may Allah be pleased with her) when out of the state of ihram, and consummated the marriage with her when out of the state of ihram, and I was the messenger between the two of them."
