Does vomiting break the Fast?

بسم اللہ الرحمن الرحیم
الجواب بعون الملک الوھاب اللھم ھدایۃ الحق والصواب

Vomiting involuntarily will not cause the fast to become void, even if it is a mouthful, i.e. a large amount. If caused him/herself to vomit a mouthful [intentionally] and remembered that he/she was fasting, the fast will become void, but if it was not a mouthful i.e. a small amount, then the fast will not break, even if it was done of’s own volition.

Just as it is stated in Bahar-e-Shariat:

If intentionally vomits a mouthful and he remembers that he is fasting, then the fast is definitely broken. If he vomited less than a mouthful, the fast will not break. If he vomited involuntarily, then whether it is a full mouth or not, and in any case, if it went back into the throat, or if he pulled it back into the throat, or if it did not go back, or even if he did not pull it back in, and if it is not a mouthful, the fast will not break, even if it went back into the throat or if he pulled it back himself.
