The ruling on inserting an endoscope while fasting
Machine translationRead the Arabic original
The questioner : A questioner says: A person inserted an endoscope while he was fasting, and then he vomited
The Shaykh : into his stomach.
The questioner : Yes, and he was fasting, then he vomited. What is the ruling on his fast?
The Shaykh : First, the instrument used for viewing, which is inserted into the stomach, must be free of any accompanying medication. If it contains medication or oil to facilitate its insertion, it breaks the fast, and it is not permissible to use it while fasting if the fast is obligatory. However, if the instrument contains nothing—neither medication nor oil—and it is inserted, there is no blame on him. But he must instruct the doctor to remove it if he feels he is about to vomit, so that he does not vomit intentionally. This applies if the fast is obligatory. If the fast is voluntary, the matter is easy; if the fast is invalidated, he owes nothing.
