What is the ruling on intentionally vomiting by inserting a finger into the throat after overeating, with the intention of feeling relief?

Fasting is invalidated if a fasting person intentionally vomits during the daytime in Ramadan, and they must make up for that day. However, if vomiting overtakes someone, they do not have to make up for it, as the Prophet (peace be upon him) said: "Whoever is overcome by vomiting does not have to make up for it, but whoever intentionally vomits must make it up."

If vomiting occurs unintentionally outside of Ramadan's daytime, there is no harm in it. However, if a person makes it a habit after overeating, this is a bad habit similar to the practice of the pagan Romans, and it is considered a waste of money. Goodness lies in following the Sunnah of the Prophet (peace be upon him) in moderation in eating and drinking. He (peace be upon him) said: "No human ever filled a vessel worse than his stomach. A few morsels are sufficient for the son of Adam to keep his back straight. But if he must eat more, then a third for his food, a third for his drink, and a third for his breath."
