400. In the case of little istihaza the woman should perform separate Wudhu for every prayer and should change the pad. And if some blood is found on the outer part of her private parts she should make it Pak with water.
401. In the case of Mutawassita, it is an obligatory for a woman to make one Ghusl everyday for her Fajr prayers, and she should act accordingly to the rules of little Istihaza as explained in the foregoing rule untill tomorrow Fajr. If she does not do Ghusl intentionally or forgetfully for her Fajr prayers , she should do Ghusl before Zuhr and Asr prayers. And if she misses even that, then she should do Ghusl before praying Maghrib and Isha. This she would do regardless of whether bleeding continues or stops.
402. In the case of excessive bleeding, a woman should change the cotton or pad tied to her private parts or make it Pak with water. It is also necessary that she should do one Ghusl for Fajr prayers, one for Zuhr and Asr prayers and once again for Maghrib and Isha prayers. She should offer Asr prayers immediately after Zuhr prayers and if she allowed any lapse of time between them, she should do Ghusl again for Asr prayers. Similarly, if she keeps any time gap between Maghrib and Isha prayers, she should do Ghusl again for Isha prayers.
405. When a woman who had little Istihaza finds out after Fajr prayers that her Istihaza has developed into medium one, she will have to do Ghusl for Zuhr and Asr prayers. And if that change occurs after Zuhr, Asr prayers, then she will do a Ghusl for Maghrib and Isha prayers.
409. After the bleeding of a mustahaza woman has stopped, she should follow the rules of istihaza only for the first subsequent prayers which she may offer. For further prayers which follow, the rules of Istihaza would not be necessary.
410. If a woman does not know what kind of Istihaza she has, she should insert into herself some cotton and wait a while to ascertain. And when she knows which kind of Istihaza it is she would follow the rules prescribed. And, if she is sure that the type of Istihaza will not change by the time she stands for her prayers she may carry out the test before the time for prayers sets in.
411. If a mustahaza woman starts her prayers without making any investigation, but her intention is to obey the orders of Allah and act according to her duty then her prayers are valid. For example, if her Istihaza was little, and she acted according to its rules, her prayers will be correct and valid.
But if she did not have the intention of obeying Allah or following the rules, her prayers would be invalid. For example, she followed the rules of little Istihaza while in actual fact she was in the medium one, her prayers would be invalid.
412. If a mustahaza woman cannot discern about her Istihaza she should act according to the minimum certitude. For example, if she does not know whether her Istihaza is little or medium she should follow the rules which are prescribed for little Istihaza. And if she does not know whether her Istihaza is medium or excessive she should perform the rules prescribed for the medium Istihaza. But, if she knows which of the three kinds of Istihaza she has had previously, then she should act according to the rules for that kind of Istihaza.
413. If the blood of istihaza remains within the interior of the body and does not come out, it does not nullify the Wudhu and Ghusl already performed by the woman. And if it comes out, it nullifies the Wudhu and Ghusl even if its quantity be very small.
414. If a mustahaza woman examines herself after Namaz and finds no blood, she can say other prayers with the same Wudhu, even if she knows that the blood would reappear.
416. If a mustahaza woman knows that before the time for prayers comes to an end, she will become totally Pak, or if she knows that at certain time, bleeding would stop for the time required for offering prayers she should wait and offer prayers when she is Pak.
417. If a Mustahaza, after having done Wudhu and Ghusl, finds that the bleeding has ceased, and she feels that if she delays the prayers she will become fully Pak, within the time required for Wudhu, Ghusl and Namaz, she should delay the prayers, and offer them after performing fresh Wudhu and Ghusl when she has become fully Pak.
But if time for prayers is limited, it will not be necessary for her to perform Wudhu and Ghusl. She should offer prayers with the Wudhu and Ghusl which she already has.
419. Mustahaza women with little bleeding after Wudhu, and medium or excessive bleeding, after Wudhu and Ghusl, should commence their prayers immediately; but to recite Adhan and Iqamah before Namaz or performing Mustahabat, like Qnut etc., will have no objection.
432. If a Mustahaza woman neglects any one of the obligatory rules, even changing cotton, her Namaz will be void.
433. If a woman who is in little Istihaza wishes to engage in an act which requires Wudhu as a prerequisite, like touching the script of the Qur’an etc., she should make the Wudhu for the purpose.And the Wudhu made specifically for Namaz would not be sufficient.
436. Salatul Ayat (due to solar or lunar eclipse etc.) is obligatory for a Mustahaza woman and she should follow all the rules which have been explained in relation with the daily prayers.
