Q: I have this horrible habit of chewing my nails and sometimes I don't realize i'm doing it. Will that break my fast? Not that I'm trying to excuse myself, because I really don't like doing it, but I agree with Safiyah. It is from myself. Like we can swallow our own saliva. Someone said I was trying to eat myself. That's definitely not the case.
A: i suggest you don't cos there's all sorts of bacteria which can give you a poor stomach =(....also you may eat it...so better to stop then never...especially in the month of ramadan!! =) May allah shower his blessings upon all of us!! =)
