Menstruation - is a natural phenomenon that from the point of view of religion requires a special approach.
According to the Quran and the Sunnah, the husband, although he can caress his wife during menstruation, he can not have intimate relations during this period. Intimacy at the time prohibited (haram). Woman during menstruation can not perform namaz, can not make up for the missed prayers.
Like the women at the time of the Messenger of Allah (peace be upon him) she should not keep the fast during Ramadan. And all the missed days, she should make up after, in a clean period. Since it's like namaz and forbidden by the Messenger of Allah (peace be upon him) a woman during menstruation can not make circumambulation of the Kaaba, except in cases of extreme need.
A woman who is after intimacy, but before she made ablution, began menstruating, should perform full ablution.
Woman during menstruation or during the post-partum bleeding can perform dhikr and du'a. Muslim scientists approve, if a woman, with the onset of the times for prayer gives a few minutes of Dhikr and Du'a.
Menstruation - is not a state of uncleanness or defilement. This natural state, set by Allah. Therefore, the month should be treated as forgivable (ma'zarat) state, not as a state of uncleanness and defilement.
The Messenger of Allah (peace be upon him) did not approve of, even when the state junub occurring after intimacy, described by words such as impurity, defilement. Therefore, it is clear that he would not have approved if similarly characterized month
This Hadith confirms this truth:
Aisha (radyyallahu ankh) reports:
"We came out (of Medina) in order to perform the Hajj. When we reached Sarif area near the Medina, I got my period.
When I was crying (thinking that I could not make all the required rituals of the hajj), I was approached by the Messenger of Allah (peace be upon him) and said:
- What happened? You got your period?
When I answered "yes," he said:
- Monthly is the command of Allah, which He has prescribed for the daughters of Adam. (So no need to cry). You should not only make circumambulation of the Kaaba, and all the other rites of Hajj is performed, as well as all the pilgrims.
