Musannaf Ibn Abi Shaybah 1027 — A woman whose clothes are stained

Sayyidah Aishah (may Allah be pleased with her) said: One of us would have a single shift in which she menstruated and in which she was in a state of major ritual impurity (janabah); then she would see on it a drop of her menstrual blood, and she would scrape it off with her saliva.
