Does committing a sin in Ramadan invalidate the fast?
Machine translationRead the Arabic original
Question : A questioner says: I committed a sin in Ramadan. Does that invalidate my fast or not?
Answer : We do not know about this specific sin whether it invalidates the fast or not. If this sin is one of the things that invalidate the fast, then it invalidates his fast. We have mentioned the things that invalidate the fast in previous lessons. However, if it is a sin that is not related to the fast, it does not invalidate the fast. For example, if a person backbites his Muslim brothers during the day in Ramadan while fasting, this is a major sin, but it does not invalidate the fast; it only diminishes the reward of the fast. Yes.
