Answered by Shaykh Faraz Rabbani
Question: If I intentionally corrupted a Ramadan fast, can I feed 60 people 2 meals instead fasting for 2 consecutive months?
Answer: 1. No. If the fast was broken in a way that requires expiation, then for who are able to fast (and being able to fast during Ramadan is a clear sign of ability) they cannot simply feed as expiation.
2. It is recommended to do one’s makeup fasts first, because they are obligatory (fard) whereas the expiation is necessary (wajib). [Durr al-Muntaqa]
