What is the ruling regarding a father not making up for missed fasting days after seven years lived in Europe due to instability, knowing that he has performed Hajj and is 63 years old?

Fasting Ramadan (definition) is a great pillar of Islam. Whoever denies its obligation is considered a disbeliever by scholarly consensus. Whoever misses fasts must make up the days they missed. If the breaking of the fast was intentional, they must repent and seek forgiveness. The aforementioned father must make up the fasts for the seven years he did not fast. If the breaking of the fast was without a valid excuse, he must repent. His not residing in a stable place is not an excuse.

He must immediately begin making up the fasts according to his ability. If he intentionally engaged in intercourse on a day he broke his fast, he must pay a major expiation for each day he engaged in intercourse, in addition to making up the fast, even if he did not intend to fast, because he is obligated to abstain. If he engaged in intercourse forgetfully or out of ignorance of the prohibition, there is no expiation upon him.

He is obliged to pay an expiation for delaying the making up of Ramadan fasts until the next Ramadan if the delay was without a valid excuse. This expiation is approximately 750 grams of the staple food of the country for each day, and it should be given to poor Muslims.

If his inability to fast is confirmed by a trustworthy doctor, the obligation to make up the fasts is waived, and he must feed the poor (approximately 750 grams for each day). He is also liable for the expiation of delaying the making up of the fast if he was able to do so at its appointed time. Performing the Hajj pilgrimage does not waive his obligation to make up the Ramadan fasts because it is a debt owed to Allah.
