Hesitation or Change in Nīyyah of Obligatory Fasts
Issue No. 1333- If somebody is reluctant in his intention to break or not to break a specified obligatory fast or the fast of the month of Ramadan, or decides to cancel his intention of observing a fast, his fast becomes invalid. If he also intends to perform an act which invalidates the fast, for example, he decides to eat something, his fast becomes invalid even if he does not eat anything at all. However, if he has not paid attention at that time that (for example) the said act invalidates the fast, his fast remains valid.
