Ramadhaan & Fasting

Q: What is the amount to be paid for kaffarah for fasts.

Q:

1. If a person has fasts pending for a vow that he has made without him having specified the date, can he fast these fasts of zul hijjah or should he keep those fasts first?

2. If he has to fast for his vow in these 10 days will he acquire the sawaab of the zul hijjah fasts? Also if a woman fasts ramadaan qadhas in these days does she get the sawaab of zul hijjah fasts?

Q: Is it true that one cannot fast on 11th, 12th and 13th Zul Hijjah? 

Q: What is the ruling for a fasting woman who inserts portion of the tissue into the private part for istinjaa? Will her fast break through this?

Q: If I have not kept many fasts without any valid reason in my childhood, when I became baligh how do I fulfill it? Do I have to make kaffara? What is the kaffara and what if the amount of fasts is so many and I don't remember? 

Q: Is there any punishment for a person who deliberately misses fasts continuously without any reason and has it in mind to make up for those days after Ramadhaan?

Q: I am able to fast though I am not in good health. Lately I am suffering from bouts of fever for no apparent reason. I know that fever means that I have to break my fast. If I develop fear say an hour before Ifthaar, how long can I postpone Ifthaar and how close to Ifthaar can I break my fast so that my fast would still be valid for the day?

Q: If I keep my qaza fasts and nafl fasts without eating sehri, will the reward be less?

Q: While fasting, haidh began early in the morning, a few hours after fajr.

1. Is there qadha for this fast?

2. Is the ruling different for fardh fast and nafl fast?

Q: How we can decide when it's the right time to stop sehri?
