Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrated that the Prophet (peace and blessings be upon him) led the Zuhr prayer one day, and a man stood behind him (in the congregation) and recited "Glorify the name of your Lord, the Most High" [Surah al-A'la: 1]. When he finished the prayer, he (peace and blessings be upon him) asked: "Who was the one reciting?" The man said: It was I. He (peace and blessings be upon him) said: "I realised that one of you was contending with me over it."
