I am a recent convert to Shia Islam and I was breaking my fasts right at sunset as I did not know I had to wait some minutes longer. Are my fasts valid for those days or do I have to make them up later?
If you thought that time of breaking the fast has definitely come, and based on that you broke you fast according to that, your fast is valid.
‘If you wish to practice precaution by fasting those days again, you can do so but it is not obligatory.
Wassalam.
