Aisha reported: A woman asked the Apostle of Allah ﷺ how to wash herself after menstruation. She mentioned that he taught her how to take bath and then told her to take a piece of cotton with musk and purify herself. She said: How should I purify myself with that? He (the Holy Prophet) said: Praise be to Allah, purify yourself with it, and covered his face, Sufyan bin Uyaina gave a demonstration by covering his face (as the Holy Prophet ﷺ had done). Aisha reported: I dragged her to my side for I had understood what the Apostle of Allah ﷺ intended and, therefore, said: Apply this cotton with musk to the trace of blood. Ibn Umar in his hadith (has mentioned the words of Aisha thus): Apply it to the marks of blood.
