Dua While Opening Fast
اللَّهُمَّ اِنِّى لَكَ صُمْتُ وَبِكَ امنْتُ وَعَليْكَ تَوَكّلتُ وَ عَلى رِزْقِكَ اَفْطَرْتُ
Allahumma inni laka sumtu wa bika aamantu wa alayka tawakkaltu wa ala rizq-ika-aftartu
Meaning:
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.
