The Evidence for the Impurity of Vomit and What Remains of It in the Mouth

Question:
It is not like a shaykh; what is the evidence that it is considered impure? Even though this is accepted in the mouth, and if some of it falls, a portion remains in his mouth, so he gathers it, or he raises what is in his mouth with what he desires, does he say that he has swallowed impurity?

Answer:
The evidence is that it comes out of the stomach; it comes out of the stomach, so it is like feces and urine that come out of the mouth, because it is all regurgitated matter coming from the stomach. Whether it exits through the two passages or through the mouth, as long as it is from the stomach, it is impure. This is the reasoning for the impurity: that it is an exit from the stomach. Whatever exits from the stomach is impure, whether it exits through the two passages or not. The impurity is not due to its exiting through the two passages; the cause of the impurity is that it is an exit from the stomach. They said: If it exits from the body, whether it exits from the mouth, or if doctors create an exit other than the two passages—for example, they open it up, which happens often, may Allah keep us safe—often something befalls the two passages, so the doctors open it up, and urine and feces come out from it. Do you say that this does not break the wudu?
Because it is an exit from the stomach; this is the cause. As for what remains in the mouth and the throat, it is excused. The mouth is stirred around; the mouth is stirred around. But if it happens that something remains in the throat, it is excused because one does not know about it. Yes.
