Behave respectfully when you are fasting; use your fast as a shield against bad behaviour; practice self control; remind yourself and others that you are fasting if someone tries to fight with you or abuse you while you're observing your fast .

This hadith, narrated by Abu Hurairah, speaks about the importance of fasting. It teaches us that fasting is a shield which can protect us from bad behavior. When we are fasting, we should not behave in an obscene manner or foolishly. If someone fights or abuses us while we are fasting, we should say “I am fasting” as a reminder to ourselves and others that our fast is protecting us from engaging in any negative behavior. This hadith also teaches us the importance of self-control and how it can help protect ourselves from engaging in any negative behaviors or actions.
