Does It Invalidate The Prayer If A Person Who Is Not A Member Of The Congregation Corrects A Mistake Of The Imam?

Does it invalidate the prayer if a person who is not a member of the congregation corrects a mistake of the imam?

If an imam recites wrongly during qiraat or forgets a part he needs to recite, correction or reminder of a member of congregation invalidates neither the prayer of the imam nor that of the congregation (Marghinani, al-Hidayah, II, 6-8, Mawsili, al-Ikhtiyar, I, 210). However, the prayer becomes invalid in the event that a person who is not a member of the congregation corrects imam’s mistake and the imam acts accordingly. Because this act is regarded as a learning and teaching (Zaylai, Tabyin, I, 156; al-Fatawa al-Hindiyyah, I, 110). This correction is not regarded as an act that invalidates prayer for some other schools. According to a narrative, Uthman (ra) corrected the mistake of a person who was establishing prayer near him while he was sitting in the Maqam Ibrahim (Ibn Qudamah, al-Mughni, II, 460).
