Haiz, Istihaazah & Nifaas

Q: It is mentioned in a fatwa regarding a mutahayyara that if she is in doubt as to whether her haidh has ended or not, she will take ghusl for each salaah time and perform the salaah of the time. When the next salaah time comes, she will take ghusl and before performing the salaah of that time she will perform the last salaah again as a precaution" So what does it mean as a precaution perform the last salaah again. How is that being cautious?What are they being cautious of? 

Q: If a woman has completed her haiz, can she do intercourse with her husband without making ghusl although she has no bleeding or any trace of haiz but she did not make ghusl for haiz?

Q: If a woman is mutahayyarah (istihazaa forgot her habit) and she is doing ghusl for every salaah thereafter does she has to do qadha again for those salaahs. Can you explain the hukm of muthayaraah who had forgot everything (adat, tuhr, gap, etc.)?

Q: I have questions related to Islamic activities like prayer, reciting Quran and fasting, sexual relations, etc. My wife was pregnant for 2 month's but the growth of the embryo has stopped after 1 month(4 weeks). After 2 month's we came to know the problem and the doctor advised to get D&C (abortion). Now even after 12 days, her menstrual cycle has not started and she is just spotting after 1 or 2 days on her pad. I want to know Islamically, do we consider it as menstrual bleeding or istihada?

Q: I am unsure of how to count my period days as, usually, even when I am not bleeding or on my period I have a small amount (the size of a two rand coin approx) slightly yellow/cream colored discharge or perhaps this may even be from sweat as I don't feel it coming out. So, when I count my period days, towards the end of my period about 8 days in, I see this yellow/cream color on my sanitary towel. Would this be considered as the end of my Haidh as it is the normal color that is always on my sanitary liner? Do I make a ghusl when I see this color or do I wait a full ten days. I am unsure as there is never actually no color on my liner, and, all of the masalas that I have read say that you have to wait for your sanitary liner to be completely white,but, I never experience that my sanitary liner is completely white.

Q: If a lady has periods for only 1-2 days and then her bleeding stops... Should she take bath after 3-4 days or should wait for 7 days?

Q: My wife is passing through the period of nifas (the blood which comes after the birth). She stopped bleeding before the completion of 40 days and she took a bath. Now can I have sex with her? 

Q: Can I do umrah after 4 days of periods. My bleeding has stopped so can I do umrah?

Q: A girl spotted on the 6th of March, Tuesday, at 2:00 PM. Then only on Thursday the 15th of March at 9:00 PM she started bleeding. Does all the days from the 6/03 till the 15/03 count as her haiz?

Q: Does a woman have to pray during the periods of dryness during the beginning of her menses? For example, a woman who normally has a heavy period that lasts over a week, notices a small burst of blood during the time she is expecting her period, but then experiences a day of two of dryness (though she expects her period will resume), then the blood starts really flowing.

Does she have to pray during the day or two? If so, does she have to make ghusl before praying? How many days is the period of purity according to the hanafi Madhab?

Lastly, does a woman consider her menses started if the blood is still in the inside of her private part (has not yet flowed to the outer, visible part)? For example, if she inserts a piece of tissue into the inner part of her private part (inside the hole, where it is not visible) and it comes back with blood, but the blood does not flow to the outer part for about half of a day (such that if she wipes the outer part, the tissue comes back clean), is she still considered on her period during this time?
