The ruling on a traveler resuming his fast after intending to break it
Machine translationRead the Arabic original
The questioner : A traveler intended to break his fast but did not find anything to break it with. When he was close to the time of sunset, he resumed his intention to abstain. What is the ruling on his fast?
The Shaykh : That is, a traveler intended to break his fast, meaning he cut off the fast. Then he wanted to return to fasting anew when he saw that Maghrib was near. Is this valid or not? We say it is not valid, because when he intended to break the fast, it was broken, even if he did not eat or drink. As long as he intended to break the fast, it is broken. Even if he resumes the fast, it is not valid, because the obligatory fast must be from before the dawn. Yes.
