Q: My mom runs a baking business from home, where she makes biscuits, etc. She has received a request from a number of Hindu ladies asking her if she can prepare some stuff for Diwali. Is this permissible?
A: It is permissible to sell food to non-Muslims, be they Hindu, Christians, Jews, etc. and regardless of the occasion for which they are buying that food. It is totally permissible.
