The recitation of the prayer is wrong 3295367484

One of the Imams recited the Qur'an instead of the Qur'an. For example, كَيْفَ فَعَلَ رَبُّكَ was replaced by ربك. In this situation, when it was said to be corrected from behind, Imam Sahib also corrected and recited the whole verse. Then in the second rak'ah he also went from one surah to another and continued to recite without any break in the middle. Due to such a situation in the prayers, the worshipers are divided over the purity of the prayers. There was no harm in the prayer due to the mistake mentioned by one party; Rather, the prayer has become pure and valid. On the other hand, the idea of the other party is that the prayer was not valid because of the mentioned mistake, so they performed the prayer again. What is the correct solution to the above problem in the eyes of Quran and Hadith? 1127956467
