In the month of Ramadan, I vomited for ten days and did not break my fast. Do I have to make up those days or not? May Allah reward you with good.

If the vomiting was by choice, then you must make up the days, because of the saying of the Prophet ﷺ.

Whoever is overcome by vomiting does not have to make up the fast, but whoever vomits intentionally must make it up. But if it was involuntary,

and you did not intend it, and it happened without your choice, then you are not accountable. This is based on the mentioned hadith. But if you were able to

do it by your own choice during those ten days, then you must make up all those days, because the fast is invalidated by that. May Allah reward you with good.
