What is the ruling on worshippers raising their voices to denounce the Imam after the prayer for not correcting a mistake in recitation?

He who raises his voice to the Imam has erred, for the Imam is an exemplar and must be revered. It is better for the task of correcting the Imam to be undertaken by those immediately behind him from the first row, as their voices can be heard more easily, and the correction should be limited to one person so as not to confuse the Imam. Those behind the Imam should be people of intellect and knowledge, and everyone should avoid disagreement and raising their voices, as the Messenger of Allah, peace and blessings be upon him, said: "Let those of you who are mature and wise be near me, then those who are next to them – he said this three times – and beware of the clamor of the markets." Correcting the Imam is generally permissible and not obligatory except for Al-Fatiha, and the prayer is valid despite the Imam's error in recitation as long as the error is not in Al-Fatiha.
