Suhūr (Arabic: سحور suḥūr, lit. "of the dawn", "pre-dawn meal"; also spelled suhoor, sahur, or sehri) is an Islamic term referring to the meal consumed early in the morning by Muslims before fasting, sawm, before sunrise during the Islamic month of Ramadan. The meal is eaten before fajr prayer. Suhur as the morning meal is matched by Iftar as the evening meal, during Ramadan, replacing the traditional three meals a day (breakfast, lunch and dinner), although in some places dinner is also consumed after Iftar later during the night. Being the last meal eaten by Muslims before fasting from dawn to sunset during the month of Ramadan, suhur is regarded by Islamic traditions as a benefit of the blessings in that it allows the person fasting to avoid the crankiness or the weakness caused by the fast.
According to a hadith in Sahih Bukhari, narrated Anas bin Malik: The Prophet said, "take suhur as there is a blessing in it."
The mesaharati (public waker) is a public waker for suhur and dawn prayer during Ramadan. According to the history books, Bilal Ibn Rabah was the first Mesaharati in Islamic history as he used to roam the streets and roads throughout the night to wake people up.
