Does a fasting person break his fast by spitting his saliva out to the space between his lips and then swallowing it?

Question : This questioner asks: Is it true that some jurists say that a fasting person breaks his fast if he spits his saliva out to the space between his lips and then swallows it?

Answer : Yes. Some scholars have said that if a person spits his saliva out to the space between his lips, it has separated from his mouth. If he swallows it, it breaks his fast according to some scholars. Therefore, the precaution is not to swallow it after he has spit it out to the space between his lips, because it has separated from his mouth. However, if it is in his mouth, it does not break his fast, even if a person collects his saliva or if phlegm reaches his mouth and he swallows it; he does not break his fast. But he should not swallow the phlegm after it reaches his mouth. Yes.
