Explanation

Yazīd ibn al-Asamm says that the Mother of the Believers Maymūnah bint al-Hārith (may Allah be pleased with her) told him that the Messenger of Allah (may Allah's peace and blessings be upon him) married her when he was outside the state of Ihrām. When he married her, he was not assuming Ihrām for Hajj or ‘Umrah. Yazīd then mentioned his relation to Maymūnah (may Allah be pleased with her) as she was his maternal aunt, and the maternal aunt of Ibn ‘Abbās (may Allah be pleased with him) as well. This indicates his close relationship with Maymūnah, and proves that the Prophet (may Allah's peace and blessings be upon him) was not in the state of Ihrām as Ibn ‘Abbās said.
