The Prophet ﷺ said, "The two units of prayer before Fajr are better than this world and everything in it."
عن النبي ﷺ قال: ركعتا الفجر خير من الدنيا وما فيها.
Muslim narrated it in "The Travelers" (725) from Muhammad bin Ubayd Ghubari, who said, "Abu Awana told us, from Qatada, from Zurara bin Awfa, from Saad bin Hisham, from Ayesha," and he related it.
