The Prophet ﷺ said, "The two rakahs of Fajr are better than the world and everything in it."
عن النبي ﷺ قال: ركعتا الفجر خير من ﷺ الدنيا وما فيها.
Muslim narrated it in Al-Musafirin (725) through the route of Abu Awana, from Qatada, from Zurara bin Awfa, from Saad bin Hisham, from Ayesha, and he mentioned it. In another version, "The two of them are dearer to me than the entire world."
