Questioner: The last question: does putting a speculum inside a person for medical purposes break the fast?
Answer: “If putting the speculum inside, as I think and of course this is not my specialty, and I know now that the earth is full of doctors. So like this I say based on what I know about this…the one who enters a speculum inside himself and there is no medicine with it like with a puffer, for example, if it is only a piece of iron that goes inside to the desired place to examine it and then is removed, then there is no breaking of the fast with this. This is because it is not in the meaning of food nor drink…”
