Ramadhaan & Fasting

Q: Is it permissible to use Flavoured Lip Ice whilst fasting?

Q: When inserting eye drops into the eye, the fluid in the eye drains in the sinus passages (the nose and throat). Does this still validate the fast?

Q: Is it permissible for one to fast on only a Friday (nafl/qadha) without fasting on any other day of the week? 

Q: What is the ruling about trimming ones hair and moustache and clipping of one’s nails whilst fasting? Is it permissible?

Q: You stated that a sister should commence with fasting before fajr time has entered. If I did not misunderstand is that the case with nafl? I wanted to clarify if there is any difference in Ramadan. We read in Turkish kitabs that in Ramadan we should wait until zawaal with fasting and if we are sure that we are clean before zawaal and haidh has ended, then ghusl should be taken and make niyyat and fast. Please correct me if I understood wrong because I was practicing on that.

Q: What is the last time one can make intention for fasting, because for a woman this is important to know especially if she thinks that ghusal would be fard in the next few hours. I would like to know when can make our intention for Qadha fasting, waajib fasting and nafl fasting.

Q: Can one keep any qadha fasts as joint fasts with the six fasts of Shawaal or must one keep them separately?

Q: I just wanted to find out if my fast would be accepted as I'm working in a licensed restaurant. I personally don't think it would, but would like to get some advice about it from someone who knows better.

Q: My wife missed Ramadhaan fasts due to menses. She also made niyyat to keep fast already due to the execution of some work.  My question is for which one she needs to give first priority (Whether it is Ramadhaan Fast or the other one?)

Q: Will the fast break if water enters the anal passage while fasting? How then should a person make istinja whilst fasting?
