But if she desires to offer once again...
But if she desires to offer once again, as a precautionary measure, the daily prayers which she has already offered or to offer, once again with congregation, the prayers which she has offered individually, she should perform all the acts which have been mentioned with regard to istihaza In case, however, she offers 'precautionary prayers' "forgotten sajdas'; "forgotten tashahhud " and "sajda-al-sahu " immediately after the prayers it is not necessary for her to perform acts relating to istihaza 409.
After the blood of the mustahaza woman has stopped, she should perform acts relating to istihaza only for the first prayers which she is going to offer and performance of those acts is not necessary for the subsequent prayers. 410. If a woman does not know what kind of istihaza she has she should, when she intends offering prayers, place some cotton in her vulva and wait a little and then take it out.
And when she comes to know of which kind her istihaza is she should perform the acts which have been prescribed for it. However, if she knows that her istihaza will not change till the time she wants to offer prayers she can make investigation about herself before the time for prayers sets in. 411. If a mustahaza woman engages herself in prayers before making investigation about herself and if she intends obeying the orders of (and acts according to her legal obligation e.g.
if her blood is slight and she performs the acts prescribed for slight blood her prayers is in order. And if her intention in offering prayers is not to obey the orders of Allah or she does not act according to her legal obligation e.g. if her blood is medium, but she performs acts which are prescribed for the women having slight blood her prayers is void. 412. If a mustahaza woman cannot make investigation about her she should act according to her definite legal obligation.
For example, if she does not know whether her blood is slight or medium she should perform the acts which are prescribed for slight blood. And if she does not know whether her blood is medium or excessive she should perform the acts prescribed for the medium blood. However, if she knows which of the three kinds her istihaza she had previously she should act according to the legal obligation for that kind of istihaza. 413.
If at the time of its initial appearance the blood of istihaza remains within the interior of the body and does not come out, it does not nullify the ablutions and bath already performed by the woman.
