Prayer (Kitab Al-Salat)

Dawud :: Book 2 : Hadith 664

Narrated Al-Bara' ibn Azib:

The Apostle of Allah (peace_be_upon_him) used to pass through the row from one side to the other; he used to set out chests and shoulders in order, and say: Do not be irregular. And he would say: Allah and His angels bless those who are near the first rows.
