Sayyiduna Bara’ bin Azib (may Allah be pleased with him) narrates that when we would stand for prayer, the Prophet Muhammad (peace and blessings be upon him) would hold our chests and shoulders and say:“Do not be uneven in your rows, otherwise discord will arise in your hearts.”He would also say:“Allah Almighty and the angels send blessings upon those in the first row or those in the front rows.”
