Must the questioner re-fast the day on which she vomited while reciting the Quran, knowing that the vomiting was a result of her attempt to remove something stuck in her throat?

The ruling on fasting in this situation is divided into two steps:

Step One: Is the fast valid or invalid? The fast is invalidated if the fasting person intentionally vomits. However, if vomiting overwhelms him and occurs involuntarily, his fast is not invalidated, unless he intentionally swallows some of it after it reaches his mouth and he is able to spit it out. As for what remains in the throat: 1. If it came up with the vomit from the stomach, its ruling is the same as the detailed ruling for vomit mentioned previously. 2. If it was not related to vomit (such as food remnants), then if it goes down to the stomach, it does not affect the fast. If it comes up to the mouth and you expel it, it does not affect the fast. However, if it reaches the mouth and you are able to spit it out, then you intentionally swallow it, this invalidates the fast.

Step Two: The ruling on making up the fast of this day: 1. If the fast was obligatory (such as Ramadan (definition), expiation, or a vow), then it must be made up. 2. If it was a voluntary fast, the preponderant opinion is that it is permissible to break it, and making it up is not obligatory.

Note: If the attempt to dislodge what is stuck is the cause of the vomiting, and you knew that it would cause it, then this is considered an intentional act that leads to vomiting and invalidates the fast.
