Jumai' bin 'Umair said:"I entered upon 'Aishah with my mother and maternal aunt, and we asked her what the Prophet (ﷺ) used to do when one of (his wives) was menstruating. She said: He would tell us, when when of us menstruated, to wrap a wide Izar around herself then he would embrace her chest and breasts
