Menstrual Periods

Bukhari :: Book 1 :: Volume 6 :: Hadith 305

Narrated 'Aisha:

Whenever anyone of us got her menses, she, on becoming clean, used to take hold of the blood spot and rub the blood off her garment, and pour water over it and wash that portion thoroughly and sprinkle water over the rest of the garment. After that she would pray in (with) it.
