A follower stood up for the third rak'ah with his imam and forgot the first tashahhud, so the follower prostrated for forgetfulness alone after the prayer!!

Question:
May Allah reward you, Your Eminence, father. The questioner says: I prayed the midday prayer on this day, and in the second rak'ah the imam stood up from the second prostration, and I did not hear him, so I went directly to the third rak'ah without sitting for the first tashahhud, because I did not hear the imam. After the imam said the closing salam, I prostrated for forgetfulness. Is my action correct?

Answer:
The prostration for forgetfulness is dropped from you, and the first tashahhud is dropped from you because the imam bears it for you, so your prostration for forgetfulness was a mistake. Yes.
