I have read a fatwa about the invalidators of fasting, particularly regarding the openings, and I have a health issue resulting from an illness. When I enter the bathroom to relieve myself, after finishing and cleaning thoroughly, a little stool appears on my underwear after some time from entering the bathroom. This is very bothersome for me, especially when I am outside the house, whether at work, traveling, or otherwise. To get rid of this issue, I use the bathroom bidet on the anal opening and insert water into the rectum and immediately expel it, which helps remove any remaining stool. I repeat this every time I enter the bathroom. Does the entry of water from the anus while I am fasting invalidate my fast?
