Interfaith marriage is when two people decide to get married, even though they are of different religions or have no religion at all. For example, one partner might be Christian and the other partner might be Muslim. It’s important to note that interfaith marriages don’t just happen between people of different religions – they can involve people who have no religion at all and believe in different values or customs. In any case, the two people get married in spite of their different beliefs, which is a really special way to show how much they love each other.
