It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Those among you who are wise and prudent should stand close to me in prayer, then those who are next to them, then those who are next to them (step by step), and do not differ in your rows, otherwise your hearts will differ. And avoid making noise in the mosque like in the markets."
