Sinful trivialities that can erase the rewards of fasting in Ramadan is the habit of backbiting. Backbiting is the habit of talking about the faults of others. Backbiting is considered a despicable act that Allah SWT despises. In fact, in a hadith, it is mentioned that a person who talks about the faults of others is likened to eating the flesh of their own sibling. Allah SWT also warns His servants to be cautious in their speech and not to seek the faults of others.

Berbohon is often considered a trivial sin. But during the month of Ramadan, lying can erase the rewards of fasting. Lying is an act that is greatly disliked by Allah SWT. Although it does not invalidate the fast, it is better for us to avoid the habit of lying. Syekh Said Muhammad Ba'asyin in the book Busyrol Karim, explains that lying is an act that should be avoided by those who are fasting.

False oaths, although they may seem trivial, have serious consequences as they can cause the loss of the reward of fasting. In the Fatawa Lajnah Daimah (23/133), it is explained that false oaths are considered a major sin. Even atonement cannot erase it due to its severity. Those who engage in this behavior are expected to repent immediately and seek forgiveness from Allah SWT.
