Two rak'ahs of Fajr better than the world
رَكْعَتَا الْفَجْرِ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا
Rak'ata-l-fajri khayrun mina-d-dunya wa ma fiha.
"The two rak'ahs [sunnah] of Fajr are better than the world and everything in it."
Narrated by 'A'ishah. Sahih Muslim 725
A short reflection
Two units, ninety seconds. Weighed against the entire dunya. Pray them.
