It is narrated from Sayyidah Umm Salamah (may Allah be pleased with her); she said: The Messenger of Allah (peace and blessings be upon him) said to me: "O Umm Salamah, do not hurt me concerning Aishah, for revelation has never come down upon me while any of my wives was with me except Aishah; revelation came down upon me while she was with me under my blanket."
