As Salaamu Alaikum,
If during fasting, vomit comes to one’s mouth, but before one can spit it out, it goes back to the stomach again, is fasting valid?
Wa Alaikum As Salaam,
Bismillahi wa billahi at Tawfeeq
There are only two scenarios where vomit breaks the fast.
1. If a person vomits a mouthful intentionally whether he/she swallows it or not.
2. If vomit comes to a person’s mouth unintentionally, and is a mouthful, and then the person in question intentionally swallows it.
Hashiya At Tahtaawi pg 662
The definition of mouthful (vomit) is that which one cannot hold back in one’s mouth without difficulty.
Hashiya At Tahataawi pg 89
If during fasting, vomit comes to one’s mouth unintentionally and then returns to the stomach unintentionally then the fast is valid.
