What is the ruling on selling food during the daytime in Ramadan in a shop or grocery store, knowing that most customers do not fast in a non-Islamic country? And does the ruling on selling differ from that for restaurants and cafeterias?

Grocery sales in Ramadan are divided into two types: First, foods that are highly likely to be consumed immediately by the purchaser, such as ice cream and juices. It is not permissible to sell these to Muslims or non-Muslims during the daytime in Ramadan, because it aids in sin and violates the sanctity of the month. Second, foods for which the seller cannot be certain of the buyer's consumption time, such as canned goods, bread, and provisions. There is no harm in selling these during the daytime in Ramadan, because it cannot be definitively asserted that they will be used for sin, and the basic principle is permissibility. The seller is not obligated to inquire about the buyer's intention.
