1 Question: Is it permissible to eat foods prepared by Christians and Jews?
Answer: Since the followers of the past revealed religions (that is, the Jews, the Christians and the Zoroastrians) are ritually pure, many of the problems concerning the status and permissibility of the food are resolved when we live in their midst. It becomes permissible for us as Muslims to eat from their food no matter whether they touched it with their wet hands or not as long as we do not know or are not sure that it consists of what is forbidden to us, like intoxicating drinks.
2 Question: Is it permissible permissible to eat from non Ahlul Kitãb people?
Answer: A Muslim is allowed to eat the food prepared by a non-Muslim 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-Muslim 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 intoxicating drinks. As for meat, fat and their extracts, the food cooked by non-Muslims should not contain any of these. If the food contains meat and animal fat, he should be sure that they are halal .
3 Question: What is the fatwa about Ahlul Kitab? Are they clean or unclean?
Answer: The Ahlul Kitab (that is, the Jews, the Christians and the Zoroastrians) are ritually pure (tahir) as long as you do not know that they have become ritually impure (najis) by coming into contact with an impure object. You can follow this ruling when dealing with them.
