Vomiting whilst fasting
Sayyiduna Abu Hurairah has narrated that the Noble Prophet has said, ‘The fast of a person who vomits involuntarily in Ramadan will not break but if a person vomits deliberately it will break.’

Though involuntary mouthful vomiting will not invalidate the fast if one swallows even a chick-pea amount of it, the fast will become invalid. However, if the swallowed amount is less than the size of a chick-pea, the fast will not become invalid.
