What does one do if they make a mistake in recitation during prayer?

Sometimes, as you say, it happens that I forget during prayer and recite one verse in place of another, or I recite a word incorrectly, and then I remember this during the bowing or prostration, or after the prayer. What is the ruling in this case, and what should I do? Do I have to repeat the rak'ah or not?
Answer: The obligatory part in this is Surat al-Fatihah. If you recite al-Fatihah, which is al-Hamd, then the objective is achieved, praise be to Allah. If you recite an extra verse or two, or recite a verse in place of another, or forget a verse and recite another, or if a word is missing from your recitation, it does not harm you. Your prayer is valid, and you do not have to repeat the rak'ah or the prayer, praise be to Allah. In fact, your prayer is valid.
However, you should strive to recite some verses along with al-Fatihah in the first and second rak'ahs of the midday, afternoon, sunset, and night prayers, and likewise in the dawn prayer. As for the third rak'ah of the sunset prayer, and the third and fourth rak'ahs of the midday, afternoon, and night prayers, al-Fatihah is sufficient, praise be to Allah. Yes.
