Sayyiduna Abu Mas'ud Ansari (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) would touch our shoulders when forming rows for prayer and would say: "Stand straight and do not stand differently, otherwise your hearts will become different from one another. Those among you who are wise and intelligent should definitely stand closest to me, then those who are nearest to them (in understanding and intellect), then those who are nearest to the second group." Sayyiduna Abu Mas'ud Ansari (may Allah be pleased with him) said: (People!) Today you have fallen into much discord because of this very reason.
