Question: Does throwing up during prayer break one’s wudu?
Answer: Assalamu alaikum wa rahmatullahi wa barakatuh,
I pray that you are well, insha’Allah.
Vomiting a mouthful, inside or outside the prayer, would invalidate one’s ablution. Vomiting less than this amount would not invalidate one’s ablution nor prayer. [Shurunbulali, Maraqi al-Falah; `Ala al-Din `Abidin, al-Hadiyya al-`Ala’iyya]
However, excessive movement would break one’s prayer. The consideration in this regard would be whether an onlooker would consider one to be in prayer or not. Though, if unwell, one may have an excuse to break the prayer anyway.
And Allah alone gives success.
