Forgetting a Verse from al-Fatihah and Repeating the Recitation

Question:
The questioner: Honorable Shaykh, a person is leading people in prayer. He recited al-Fatihah, then remembered that he had forgotten a verse, so he repeated the recitation. Is what he did correct? And is it obligatory for him to perform the prostration for forgetfulness?

Answer:
The Shaykh: Yes. If one doubts that he left out a pillar, he must make up for it. Reciting al-Fatihah in prayer is a pillar of the prayer for the imam and the one praying alone. It is obligatory for the one praying behind the imam, and it was said to be a recommended practice. In any case, reciting al-Fatihah is necessary. There are seven verses that are necessary. If he forgets one of them, he must, he must come to it. So he recites the verse he left out and what follows it, and he completes al-Fatihah accordingly. Yes.

The presenter:
May Allah reward you. Honorable Shaykh
