Ramadhaan & Fasting

Q: When travelling overseas and the need arises to discharge sadaqatul fitr, e.g. I'm overseas on eid day, will the amount be determined by my home town or the place I'm traveling in?

Q: When a person became baaligh, he was not allowed to fast by his mother due to him being asthmatic. His mother would take out fidyah for him each year instead of him fasting. This carried on for ten years until he got married. After marriage, his wife told him to try fasting, and he managed and has been fasting ever since. Now he has reached old age, and he will not be physically able to fast the ten years fast that he missed. 

1. Will the fidyah given by his mother while he was young be sufficient as compensation for the missed fasts? 

2. If not, what can he do now to compensate for the fasts missed?

Q: Is it permissible to use an olive miswaak/olive flavoured miswaak whilst fasting?

Q: My mother is due for her eye injection in the month of Ramadan (the injection is in the eye). The doctor advises that she doesn't skip it.  Is it permissible to take it?  Will it break the fast or not? 

Q: I had the niyyah to fast, but I missed sehri and my Fajr salaah.  I was in a state of janabaah. If I woke up to make ghusl is my fast still valid?

Q: I was told that a female who wants to make itikaaf at home should allocate a specific area of her home and make itikaaf there. If she is living in a 2 bedroom apartment, can she specify the entire area of her apartment as her place of itikaaf? Can she also do this for her entire house if she is living in a big home?

Q: Does a nosebleed break the fast if the blood did not reach the mouth, but blood went down the throat through the nose only?

Q: Instead of making up for fasts that I missed due to menses of the past 3 years and last year, can I give fidyah and not keep the fast?
