It is narrated from Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The wise and intelligent among you should certainly, certainly stand close to me, then those who are nearest to them (in intellect and understanding) should stand after them, then those who are nearest to the people of the second rank should stand, and do not differ from one another (in forming rows), otherwise your hearts will become opposed to each other, and avoid the mixing and tribulations of the marketplaces.
