Is it permissible for a chronically ill person whose illness affects their fasting and who cannot afford the cost of treatment or fasting to break their fast in Ramadan without a medical permit? And will anything befall them on the Day of Resurrection if they die while not fasting?

The illness that permits breaking the fast is that which exceeds the normal limit and reaches a degree of unbearable hardship, or intense hunger and thirst. Breaking the fast due to illness is not restricted to a doctor's recommendation alone; rather, it is permissible if fasting causes unbearable hardship, or if one knows from experience that it will be difficult for them, or will delay their recovery. One may rely on the trustworthy doctor's information or on their own personal experience.
