Does perfume spray entering the mouth and swallowing saliva, while feeling the taste of the perfume on the tongue and lips but not in the throat, invalidate the fast, and is it necessary to make up for that day?

If a fasting person intentionally swallows their saliva mixed with the taste of perfume, their fast is invalidated, and they must make up for it along with repentance. This is because the presence of the taste indicates that a part of the perfume entered the mouth and was swallowed, and this invalidates the fast, even if it is a small amount. Swallowing the taste is considered an invalidator if the fasting person does so intentionally and does not spit it out.
