Is it obligatory for the congregants to correct the Imam if he makes a mistake in the recitation after Al-Fatiha, provided the meaning does not change, and what should they do if the Imam refuses to be corrected? Does the prayer become void if the meaning changes and the mistake is not corrected? Is it permissible to correct recitation errors during the Friday sermon? And what is the ruling on making a mistake in explaining the verses?

If the Imam makes a mistake in recitation – other than Al-Fatihah – a mistake that does not alter the meaning, then correction is not obligatory during the prayer, and it is preferable to inform him afterwards.

However, if the mistake corrupts the meaning, and the Imam is aware of it and insists on not correcting it after being alerted, then the prayer must be repeated.

If the mistake does not corrupt the meaning, then repeating the prayer is not obligatory, but the Imam should be advised gently and kindly.

As for correction during the Friday sermon, it is permissible if the preacher makes a mistake that changes the meaning, and this is not considered among the forbidden speech during the sermon.
