Ramadhaan & Fasting

Q: Regarding this question here http://muftionline.co.za/node/4 what about the person who inhales the smoke intentionally?

Q: Kindly tell me difference between fidya and fitrah. Also let me know about the current rates of both fidya and fitrah in rupees.

Q: Are the rules same for intentionally breaking a fast in Ramdhan, and not keeping a fast at all for no valid reason? Under what circumstances do we have to do kaffara and under what circumstances do we have to do just qadha? Does breaking a fast just because you were hungry or you felt you don't want to fast anymore need qadha and kaffara or just qadha? Does not fasting at all need kaffara as well as qadha or just qadha?

Q: I would like to know what if a pregnant woman missed her full 30 fasts in Ramaadhan? How many must she keep? Must she keep it consectively or Monday and Thursday but as soon as possible?

Q: If a pregnant women never keep her fast during Ramdhaan how may should she keep? Must she keep it consectively?

Q: Regarding kissing the wife during Ramadhan fast. I knew that it was permissibile to kiss the wife as long as it does not lead to anything further. Only recently did I become aware that only kissing without the tongue was meant as kissing with the tongue would require qadha and kafaarah due to the exchange of saliva. As kissing with the tongue is the norm I had not made that distinction till now. Am I required to perfrom qadha and kafaarah or just qadha due to misunderstanding as I see in nurul idha that kafaarah will not be required if someone misunderstood the hadith?

Q: I was fasting one day in Ramadan and I didn't know that if one gargles and water goes down one's throat then the fast is invalid. So one day I was performing ghusl and I gargled 3 times and I may have accidentally swallowed some water. Is my fast invalid?

Q: In Ramadhan, if I perform ghusl e janaabat before zohar prayers and not before the fajar prayers, is my fast valid in this case?

Q: My friend came to my house during Ramadhan. He was not fasting due to some illness. Should I offer him food or not because it was Ramadhan?

Q: I understand that one is allowed to change his clothes during Itikaf. In the Haram Shareef at Makkah and Madinah since there is no privacy, is it ok if one changes his clothes in the toilet when one goes to attend nature's call? Of course care is taken that one does not leave the Haram only for changing the clothes but does it when it is unavoidable to leave to fulfil the need to go to the toilet to relieve oneself.
