Sayyida Umm Salama (may Allah be pleased with her) narrated: I was lying with the Prophet (peace and blessings of Allah be upon him) under a single sheet when I got my period. I quietly slipped away and changed my menstrual clothes. The Prophet (peace and blessings of Allah be upon him) asked, "Have you got your period?" I replied, "Yes." Then he called me, and I lay with him under the sheet.

Sayyida Umm Salamah (may Allah be pleased with her) said that I and the Noble Prophet (peace and blessings be upon him) performed ghusl for janabah from the same vessel.
