Hawzah News Agency – Is it permissible to eat food prepared from non-Ahlul Kitãb (i.e. Those who are neither Christians, Jews, nor Zoroastrians) people?
Answer: A Muslim is allowed to eat the food prepared by someone who is not from Ahlul Kitãb [for example, a Hindu or a Buddhist], provided that he does not know or is not sure that the non-Ahlulkitab touched the food with wetness; and provided that he does not know or is not sure that the food consists of what is forbidden to him like for example, Haram meat, fat and their extracts.
