Q: Due to the stone-forming nature of my kidneys, I ought not to fast during the
blessed month according to the advice of a specialist doctor. However, I don’t
want to break my fast. Assuming my drinking three cups of water – on either one
or three separate turns – during the day, would enable me to fast, may I fast
under such circumstances?
A: Assuming that the prevention of renal problems requires one to drink water,
or other liquids, during the day, fasting no longer is obligatory; moreover, it
will not be permissible. Drinking water, under such circumstances, will nullify
one’s fast.
