What is the ruling on decorating a dining table with candles?

The default rule for customs is permissibility, but if they are associated with religious prohibitions, such as imitating disbelievers or holding false beliefs, then they become forbidden. Decorating a dining table with candles falls under this category, as lighting candles in some religions symbolizes the entrenchment of false beliefs, such as in Buddhism and Christianity. In their temples, it symbolizes religious sanctity, offering sacrifices, and expelling evil, which contradicts the Islamic doctrine of Tawhid (monotheism). Therefore, to absolve oneself of responsibility and to be more cautious in matters of religion, it is best to avoid this custom, especially since it also involves a form of extravagance.
