If the imam makes a mistake in the loud prayer, should the follower correct him?

Q: If the imam makes a mistake in the recitation during the loud prayer, such as omitting a verse or part of a verse, or changing the wording of the verse by mistake, or something similar, should the follower correct him?

A: If the imam makes a mistake in the recitation by omitting a verse or committing a grammatical error, it is prescribed for those behind him to correct him. If the mistake is in Surat al-Fatihah, it is obligatory for those behind him to correct him, because reciting it is a pillar of the prayer, unless the error does not change the meaning of the verse, in which case correction is not obligatory, as in the case of using the nominative case for or or something similar.
