“Whoever prays fajr is under the protection of Allaah. Do not put yourselves in a situation where Allaah has to call you to account for your negligence.”

(Reported by al-Tabaraani, 7/267; Saheeh al-Jaami’, no. 6344).

“Angels come to you in shifts by night and by day. They meet at salaat al-fajr and salaat al-‘asr, then those who had stayed with you at night ascend, and are asked by the One Who ...
knows better than they: ‘How did you find My servants?’ They say, ‘We left them when they were praying, and we came to them when they were praying.’”

(Reported by al-Bukhaari, al-Fath, 2/33).
