Is it better for a sick person to break their fast or to fast while enduring hardship?

If fasting becomes difficult for a sick person, it is better for them to break their fast and make up the days they missed. This is because it involves taking advantage of the concession and ease granted [by Allah]. It is disliked for them to fast while experiencing hardship, and their fasting might even be forbidden if they fear harm. Some scholars have gone further, stating that it is recommended for a sick person who can fast but with harm and difficulty to break their fast, and that whoever fasts in such a state has committed a disliked act.
