What is the ruling on one who fasts some days and breaks the fast on others?

The questioner : In this session, we want to know the ruling on one who fasts some days and breaks the fast on others.
The Shaykh : The answer to this question can be understood from what has come before. It is that this person who fasts one day and leaves one day does not leave Islam, but he becomes an open sinner for abandoning this great obligatory duty, which is one of the pillars of Islam. He does not make up the days he broke his fast, because making them up would benefit him nothing, for they will not be accepted from him. This is based on what we mentioned previously: that if a person delays a time-bound act of worship from its specified time without an excuse, it will not be accepted from him.
The questioner : May Allah reward you,
