(9) Liquid enemas
1- If a sa`im is compelled to use a liquid enema due to a disease or something else, would that harm the correctness of his sawm?
A: Using liquid enemas for a sa`im is haram and it would invalidate his sawm, even if it was to treat disease.
2- If a sa`im had used liquid enemas in a way that the liquid did not come up into his body but just entered into the anus, would this break fasting?
A: It is based on obligatory caution to abstain from such an act.
