What about temporary and chronic sickness regarding fasting and what is the ruling of the sick person in both cases? May Allah bless you.

In the case of chronic sickness, one ought to give the compensation of feeding. He neither has to fast, nor to make up the fasting, nor to attempt to fast to know whether he will be able to continue or not, for his sickness thus may grow severe. But with regard to temporary sickness, one does not give compensation but waits until he gains recovery to make up the fasting. This is the difference between the two cases: the ruling of the first case is to give the compensation of feeding while the ruling of the other is to wait until he can make it up after recovery.
