The ruling on fasting to make up missed days, one day after another
Machine translationRead the Arabic original
Question:
Another questioner: Shaykh, he asks: Is it permissible to fast the days of making up missed fasts one day after another?
Answer:
Yes, there is nothing wrong with that. You may fast them consecutively or you may fast them separately; there is nothing wrong with that, as long as there is not only the number of days you owe from the previous Ramadan left before the new Ramadan begins. In that case, it is obligatory for you to fast the days you owe before the new Ramadan enters. Yes.
