Breaking the Fast on Inadequate Grounds

1. If you broke your fast without a Deeni-conscious physician telling you to do so, or merely assuming that the fast could be harmful to you but you have no previous experience, then you will have to keep Kaffaarah (60 days consecutive fasting after Ramadhaan).
2. And if you never kept a fast in the two cases mentioned then you are sinful.
