in the second month, he said that she sits [refraining from prayer] during the black blood in the third month, because she does not know that she is a possessor of discernment (mumayyiza) before that. If she saw in a month five [days] black, then it became red and was continuous, and in the second [month] the same, and in the third [month] it was all red, and in the fourth she saw five [days] red, then it became black and was continuous, she sits [during] the time of certainty in the three months, and in the fourth, she has no discernment, so she reverts in it to six or seven days, according to the most famous of the narrations, unless we say: A habit is established by two occurrences, so she sits during the third and fourth months five [days] by five [days].

It was narrated by Abu Dawud, who said: "After the period of purity." Our evidence is the saying of the Almighty: "And they ask you about menstruation; say, 'It is an impurity'" (Quran 2:222), and this encompasses both yellow and turbid discharge. Al-Athram narrated with his chain of transmission from 'Aisha, may Allah be pleased with her, that women used to send her a container (durjah) containing cotton...
