إِنِّي صَائِمٌ إِنِّي صَائِمٌ
Inni sa'im, inni sa'im
I am fasting, I am fasting. (Say this when provoked while fasting.)
The Prophet ﷺ said: "Fasting is a shield. When one of you is fasting, he should not use obscene language or act ignorantly. If someone insults him or tries to fight him, let him say: 'I am fasting, I am fasting.'" This serves as both a reminder to yourself and a notice to the other person.
