The document discusses the Muslim practice of Sahur, which is the pre-dawn meal eaten before the daily fast during Ramadan. It notes that Sahur is mentioned in the Quran and was a practice of the prophet Muhammad, who preferred taking it in the late hours of the night. Sahur provides sustenance for the fast and is considered blessed. Muslims are permitted to eat and drink until the signs of dawn appear, at which point they must complete their daily fast until nightfall.
