It was narrated that ‘Aa’ishah (may Allaah be pleased with her) said: “The Prophet (peace and blessings of Allaah be upon him) did not adhere more firmly to any naafil prayer than the two rak’ahs of Fajr.” Narrated by al-Bukhaari, 1163; Muslim, 724. ----- Concerning the virtue of this prayer, the Prophet (peace and blessings of Allaah be upon him) said: “The two rak'ahs of Fajr are better than this world and everything in it.” Narrated by Muslim, 725.
I'm not Muslim, so I don't pray Fajr, but I do want to train myself to get up for morning prayers. Apart from anything, you get to see sunrise...HOW AWESOME!! And the authors are right, even though I'm naturally a night owl, I am actually most productive around 6am. Funny stuff, but it's true!
