Wa bisawmi ghadinn nawaiytu min shahri ramadan

وَبِصَوْمِ غَدٍ نَّوَيْتُ مِنْ شَهْرِ رَمَضَانَ

I intend to keep the fast for tomorrow in the month of Ramadan

Allahumma inni laka sumtu wa bika aamantu wa alayka tawakkaltu wa ala rizq-ika-aftartu

اللّٰهُمَّ اِنِّى لَكَ صُمْتُ وَبِكَ اٰمَنْتُ وَعَليْكَ تَوَكَّلتُ وَ عَلٰى رِزْقِكَ اَفْطَرْتُ

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
