Mishkat al-Masabih 437

ʿĀʾisha said that a woman from the Anṣār asked the Prophet how to bathe after menstruation. He instructed her: ‘Take a piece of cloth scented with musk and cleanse yourself with it.’ She asked how, and he said: ‘Cleanse yourself with it.’ She asked again, and he said: ‘Glory be to Allah! Cleanse yourself with it.’ ʿĀʾisha drew her aside and explained: ‘Wipe with it where the blood was.’
