SHAFAQNA – The Grand Ayatollah Makarem Shirazi answered a question about concealing uncleaess of food to protect host’s dignity.
Question: If the host observes uncleaess (Nejasat) in food, can he conceal it to protect his dignity?
The Grand Ayatollah Makarem: This food must not be used and be aware that dignity does not suffer from such cases and wherever it is, a bite can be found for guest unless a serious urgency comes up.
