What is the legal ruling regarding not making up for many days of fasting from Ramadan for seven years, due to a chronic illness that prevents both fasting and making up for missed fasts?

It is by Allah Almighty's mercy to His servants that He has removed hardship from them, permitting the sick to break their fast. A sick person should make up for the fasts they missed if their illness is expected to be cured. However, if their illness is not expected to be cured, they must feed a poor person for each day they missed fasting. Therefore, if your illness is expected to be cured, there is no sin upon you for breaking your fast and delaying its making up as long as you are unable to do so. You must make up for the fasts you missed when you are able.
