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 with them. 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 Haram meat.
2 Question: 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.
3 Question: What is the fatwa about Ahlul Kitab? Are they ritually pure (Tahir)?
Answer: The Ahlul Kitab (that is, the Christians, the Jews 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.
4 Question: Can I eat Christians' foods that contain meat?
Answer: All kinds of food with the exception of meat, fat, and their extracts are permissible for a Muslim, even if he doubts that it might contain something which is forbidden for him.
