Giving the fasting person injection of non-nutritional elements
Q 4:
A dentist may sometimes need to give intravenous or intramuscular injections of non-nutritious substance to a patient. Does this invalidate the Sawm (Fast)
of the patient, bearing in mind that they can postpone the injection until nightfall or until after Ramadan?
A:
There is nothing wrong with injecting a fasting person with a non-nutritious substance if they are in need of it to cure a disease. However, it is better to postpone the injection until nightfall to be on the safe side.
