O Allah! I fasted for you and I believe in you and I put my trust in You and I break my fast with your sustenance.
Allahuma inni laka sumtu wa' bika aamantu wa' aalaika tawakkaltu wa' ala rizqika aftartu
O Allah, I observed the fast for your sake. I believe in You and I end the fast by eating that which You have provided me.
Allah-umma innee laka sumtu wa bika ‘aa-mantu wa ‘alaa rizqika aftartu
