Mensturation
     In Arabic, the word for menstruation (haidh) literally    means "running." Here it refers to the discharge of blood    during a woman's state of health, not from giving birth    or breaking the hymen.
         Most scholars say that its time begins at the age of    nine. If blood is seen before that age, it is not    menstrual blood, but is considered to be putrid blood. As    there is no evidence about when a woman stops    menstruating, if an elderly lady finds blood flowing it    is considered menstrual blood.
    
Requirements for blood to be considered menstrual
       Dark. Once, when Fatimah bint Abu Habash had a     prolonged flow of blood, the Prophet told her,     "If it is the blood of menstruation, it will be     dark and recognizable. If it is that, then leave     the prayer. If it is other than that, then make     ablution and pray, for it is only due to a vein."
     This is related by Abu Dawud, an-Nasa'i, Ibn     Hibban and ad-Daraqutni, who said all of its     narrators are trustworthy. Al-Hakim also related     it, and said that it meets Muslim's standards.
           Red. It is the original color of blood.
           Yellow. It is a liquid, like pus.
           A muddy color. It is an intermediate color     between black and white, like dirt.
           Malik and Muhammad al-Hassan ( and al-Bukhari in mu'allaq    form) recorded that women would send 'Aishah small boxes    with yellow-stained cotton, and she would tell them, "Do    not be in haste until you see the pure white cotton." If    the discharge is yellow or muddy during the days of    menstruation, it is to be considered as part of the    menses. During other days, it is not regarded as such.
    Umm 'Atiyyah said, "After we were pure, we did not    consider the yellow or muddy discharge to be anything."
    This is related by Abu Dawud and al-Bukhari, but without    the words "...after we were pure.. ."
