Sehri

When beginning the fast

وَبِصَوْمِ غَدٍ نَّوَيْتَ مِنْ شَهْرِ رَمَضَانَ

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

Transliteration:
Wa bi-sawmi ghadin nawaytu min shahri ramadan

Iftar

When breaking the fast

اللَّهُمَّ اِنِّى لَكَ صُمْتُ وَبِكَ امنْتُ [وَعَلَيْكَ تَوَكَّلْتُ] وَعَلَى 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.

Transliteration:
Allahumma Inni laka sumtu wa bika amantu [wa alayka tawakkalto] wa ‘ala rizqika aftartu
