Can we eat a meal that has been cooked by a non-Muslim whose religion we do not know?
Answer
It is permissible to eat the food (non-meat, e.g. pasta, salad, cake) and it is not necessary for the Muslim to question the person who prepared the food about his beliefs or disbeliefs, or whether or not he had touched the food, even if that inquiry is very convenient and natural for one who wants to ask.
