It is narrated from Hazrat Hudhaifa (may Allah be pleased with him) that once I had the opportunity to spend the night in the house of the Noble Prophet (peace and blessings be upon him). The Noble Prophet (peace and blessings be upon him) stood up to pray; one corner of the blanket was on the Noble Prophet (peace and blessings be upon him) and the other corner was on Hazrat Aisha (may Allah be pleased with her). She was in her "days" at that time, meaning she could not pray.
