question #2 Sahih Muslim 291a, Book 2, Hadith 141 : How does Islamic teaching address the purification of clothing affected by menstrual blood?

A woman came to the Messenger of Allah (ﷺ) and said: What should one do if the blood of menses smears the garment of one amongst us? He (the Holy Prophet) replied: She should scrape it, then rub it with water, then pour water over it and then offer prayer in it.
