Sehri (Suhoor) Dua
وَبِصَوْمِ غَدٍ نَوَيْتُ مِنْ شَهْرِ رَمَضَانَ
Wa bi sawmi ghadin nawaytu min shahri Ramadan
“And I intend to fast tomorrow of the month of Ramadan.”
A widely used wording of the intention; it is not established as a prophetic hadith.
The intention is of the heart
Scholars agree that the niyyah is an act of the heart and does not need to be spoken. The Sunnah at Suhoor is simply to eat late and to seek forgiveness in the last part of the night (Qur’an 51:18).
Transliteration is a guide only; recite from the Arabic where you can. References are given so you can verify each wording.
