The ruling on a woman who experiences menstruation twice in one month

Question:
I am a woman who menstruated for five days at the beginning of Ramadan, then became pure. After twenty days, my period returned for five days, but I prayed and fasted. Do I have to make them up or not?

Answer:
Yes, yes. The days you fasted while you had blood are a mistake and an abomination. You must repent to Allah for this. You must repent to Allah, because a menstruating woman does not fast and does not pray. So the days you fasted, whether the last ones or the first ones, you must make up the fasting for them, because they are days of Ramadan, and you were not in a state to fast, and you had menstruation. So your fasting on those days is invalid. Your fasting on them is invalid. You must make them up, and you must repent to Allah .
As for the prayer, it is not made up, because a menstruating woman does not pray. But you must repent to Allah for your prayer while you were menstruating, and for your fasting while you were menstruating. Allah (Exalted and Majestic is He) has relieved menstruating women and women with post-natal bleeding from fasting and praying, and He has made them make up the fasting, but not the prayer. Aisha (may Allah be pleased with her) said: "We were ordered to make up the fasting, but we were not ordered to make up the prayer."
So a menstruating woman does not pray and does not fast. Likewise, a woman with post-natal bleeding does not pray and does not fast as long as she has blood before the forty days. She must make up the fasting after she becomes pure, and they do not have to make up the prayer. They only make up the fasting, the fasting of Ramadan.
And if a woman with post-natal bleeding becomes pure before the forty days, she takes a bath. If she becomes pure when she is thirty days old, or twenty, or twenty-five, and only twenty-five, or twenty, or thirty days have passed of her post-natal bleeding when she becomes pure, she takes a bath, prays, fasts, and becomes lawful to her husband. She does not wait until the forty days are completed. It is not obligatory for her to complete the forty days. When she sees purity, she takes a bath, prays, fasts, and becomes lawful to her husband, even if only twenty, or twenty-five, or thirty days have passed of the forty.
As for if the blood continues with her until the completion of the forty days, she takes a bath at the completion of the forty days. She takes a bath, prays, and fasts, even if the blood is with her, because the limit is forty. And after the forty days have passed and the blood has not stopped, she takes a bath, prays, and fasts, and she protects herself with cotton or the like. She does not perform ablution except at the time of prayer, like a woman with irregular bleeding, until she coincides with menstruation. When the blood comes at the time of menstruation, she sits, and does not fast, and does not pray, and so on. These are matters that one should be careful about.
Likewise, if a menstruating woman’s custom is seven or eight days, and then she becomes pure in three or four days, she takes a bath, prays, and fasts, and does not wait for the remaining days in which she became pure. Because menstruation increases and decreases. So if it is seven or eight days, and she becomes pure in three or four days, she takes a bath, prays, and fasts, and becomes lawful to her husband.
Likewise, if it increases to five days, and the blood continues with her for six, or seven, or eight days, she does not pray, and does not fast until she completes it, until she becomes pure.

Question: Can the time between two periods be less than a month?

Answer: Yes, the time between them can be less than a month, and less than twenty days as well. Some scholars said: the minimum is thirteen days, but there is no evidence for that. When she sees the blood, she sits, except if what is seen is yellowish or brownish discharge after purity, in which case she does not consider them to be anything.
Yellowish and brownish discharge are like urine. She prays and fasts with them, and she cleans herself at the time of prayer, and performs the ablution for prayer at its time, when its time enters, if she has yellowish or brownish discharge, like a woman with irregular bleeding whose blood continues constantly. This woman prays and fasts, and performs ablution for the time of every prayer, and does not sit except when the time of menstruation comes. When the time of her menstruation comes, she sits, meaning she leaves off fasting and praying. And when the time of menstruation has passed, she takes a bath, prays, and fasts.

Question: Meaning the month contains a period and a time of purity?

Answer: It can contain two periods in one month.
