What invalidates the fast?

Fasting can be invalidated by several actions, including eating or drinking intentionally during the fasting period, engaging in sexual relations, or deliberately vomiting. Additionally, if a person intentionally breaks their fast by engaging in sinful behavior, this can also be considered invalidating. However, unintentional actions, such as mistakenly eating or drinking, do not invalidate the fast. It’s important to maintain the spiritual focus and intention behind the fast throughout its duration.
