Does leech treatment invalidate fasting?
- It is known that leech treatment invalidates fasting because the leech sends enzymes through the skin before or while sucking the blood. Does it invalidate fasting?
Dear Brother / Sister,
Leech treatment does not invalidate fasting. However, it is better in terms of caution not to have leech treatment while fasting unless it is necessary, or to do it after iftar in the evening.
As for the leech sending enzymes through the skin before or while sucking the blood:
Because of the liquid that it secretes, leeching can be considered like having an injection at most. In that case, according to the majority of scholars, injections that do not contain nutritious food or vitamins do not invalidate fasting; the liquid secreted by the leech has no nutritional properties; therefore, leech treatment does not invalidate fasting.
