It was narrated from 'Aishah that a woman asked the Prophet (ﷺ) about performing Ghusl following menstruation and he told her how to perform Ghusl. Then he said:
"Take a piece of cloth perfumed with musk and purify yourself with it." She said: "How should I purify myself with it?" He covered his face then said: "Subhan Allah! Purify yourself with it." 'Aishah said: "I took the woman aside and said: 'Wipe away the traces of blood with it.'"
