To what does the ruling of the woman with irregular bleeding who is a beginner revert?

The questioner : If it is irregular bleeding, or if she has no custom, meaning at the beginning of her first menstruation, for the sake of consideration.

The Shaykh : The scholars say that if the irregular bleeding is from a beginner, meaning from the first menstruation that started, meaning it flowed heavily, then it reverts to the distinguishing signs. Black is menstruation, and red is not menstruation. Thick is menstruation, and thin is not menstruation. Foul-smelling is menstruation, and not foul-smelling is not menstruation. If she has no distinguishing signs, then she reverts to the custom of most women, which is six days or seven days of every month, from the beginning of the month, if she forgot when the menstruation came. And if she knows that the menstruation came to her from the middle of the month, then the beginning of her menstruation is from the middle of the month.

The questioner : Shaykh, what is your opinion regarding the statement of those who said that the beginner with irregular bleeding reverts to the custom?

The Shaykh : Of her women, no. The correct view is that she does not revert to the number of her women as long as she has distinguishing signs. If she has no distinguishing signs, then she reverts to the custom of most women. It was said that she reverts to the custom of her women, and we mentioned previously that this is closer to the truth, because the custom of women is similar with regard to kinship.
