He said: "Then bind yourself with a cloth and observe your menses for six or seven days, in the knowledge of Allah, then have a bath and perform prayer and fast for twenty-three or twenty-four days.

Asma said: "How should I purify myself with it?" He said: "Subhan Allah! Purify yourself with it!" 'Aishah said, as if whispering to her: "Wipe away the traces of blood with it."
