The ruling on one who stands for the third unit in the tarawih prayer out of forgetfulness

The questioner : These are questions regarding change and an issue. These questions are about the tarawih prayer, and the brothers are asking about the issue of benefits. Or the issue of forgetfulness in the tarawih.

The Shaykh : If he prays, for example, three units, how does he proceed? If one stands for the third unit in the tarawih out of forgetfulness, he must return to his seat, even if he has already recited al-Fatihah. He returns, sits, recites the tashahhud, and says the taslim. Then he prostrates two prostrations. Imam Ahmad (may Allah have mercy on him) explicitly stated that if a man stands for the third unit in the night prayer, it is as if he had stood for the third unit in the Fajr prayer. It is well known that if a person stands for the third unit in the Fajr prayer, he is obligated to return, because Fajr cannot be prayed in three units. . I have heard that some imams, if they stand for the third unit out of forgetfulness and are reminded, continue and pray four units. This is truly ignorance; their ignorance contradicts the saying of the Prophet (peace and blessings be upon him) . It is obligatory for a person, if he remembers during the night prayer, and among them the tarawih, if he remembers—even after he has begun the recitation—that he must return, sit, recite the tashahhud, say the taslim, then prostrate two prostrations for forgetfulness and say the taslim.
