1)does vomitting break fast. 2) is wiping the neck a part of wudu. Please provide references.
Q: Kindly explain when does vomit invalidate fasting.
A: The Fuqahaa have explained different types of vomit. We hereby simplify
them as follows: Uninduced (involuntary) or induced. Each of the two could
either be mouthful or less than a mouthful. Thus, there exist four possible
cases: (a) Uninduced – mouthful, (b) Uninduced – less than a mouthful, (c)
Induced – mouthful, (d) Induced – less than a mouthful.
The vomit in each of these cases could either: a) Exit from the mouth, b)
Unintentionally swallowed, c) Intentionally swallowed.
Only two situations invalidate the fast, a) Uninduced – mouthful –
intentionally swallowed, b) Induced – mouthful irrespective of whether it is
swallowed or not. (Darse Tirmidhi vol.2; Darul Uloom Karachi)
It is Mustahabb to wipe the neck in Wudhu.
and Allah Ta’ala Knows Best
