Ruling 1616. Whenever a fasting person intentionally vomits, his fast becomes invalid even if he vomited out of necessity or because of illness and suchlike. However, if he vomits unintentionally or involuntarily, there is no problem [and his fast remains valid].

Ruling 1617. If at night one eats something that he knows will cause him to vomit unintentionally during the day, his fast will be valid.

Ruling 1618. If a fasting person feels sick and the cause of this is something natural, such that it could not commonly be said that he made himself feel sick, then even if he can restrain himself from vomiting, it is not necessary for him to do so and his fast will be valid.

Ruling 1619. If bits of food or other tiny items enter a fasting person’s throat and go down to an extent that it could not be called ‘eating’, it is not necessary for him to bring it out and his fast is valid. However, if the items do go down to that extent [that it could be called ‘eating’], then he must bring them out even if this requires vomiting, unless vomiting is harmful or excessively difficult (mashaqqah) for him to the extent that it could not normally be endured. In the event that he does not vomit it but swallows it instead, his fast becomes invalid. Similarly, if he brings it out by vomiting, his fast becomes invalid.

Ruling 1620.

Ruling 1622. If someone burps and something comes up in his throat or mouth, he must spit it out; and if he swallows it involuntarily, his fast is valid.
