The ruling on one who omits the middle tashahhud due to forgetfulness and remembers after standing up

Question:
The listener Muhammad Ali Sa'id, a Yemeni resident in Tabuk, says: If a person prays the Zuhr prayer and, in the first two rak'ahs, stands up without sitting for the first tashahhud, should he go back to perform the first tashahhud, or should he continue his prayer? Please inform us. May Allah reward you with good.

Answer:
He should continue. The sunnah is that he continues. When he completes his prayer, he prostrates two prostrations before the taslim for forgetfulness, if he completed standing and did not remember until after he had completed standing. The sunnah for him is to continue. When he finishes the tashahhud and the supplication, he prostrates two prostrations for forgetfulness before the taslim, as the Prophet (peace and blessings be upon him) did. In some of his prayers, Zuhr or 'Asr, he forgot the first tashahhud and stood up, and the people stood up with him. When he completed his prayer, (peace and blessings be upon him), he prostrated two prostrations for forgetfulness before the taslim. He did not prevent the people from sitting, (peace and blessings be upon him). This is the sunnah. However, if he goes back and performs the tashahhud, he owes nothing. But the sunnah for him, and what is better for him, is to continue. Yes.
