The imam forgets a prostration and then remembers it

The questioner:
The questioner says: An imam prayed and forgot a prostration from the prayer, then he was reminded and he performed the prostration and the prostrations for forgetfulness, then the tashahhud. Is his action valid?

The Shaykh:
A man.

The questioner:
An imam prayed and forgot a prostration from the prayer, then he was reminded and he performed the prostration and the prostrations for forgetfulness, then the tashahhud?

The Shaykh:
If the prostration was the last thing he left out of the last rak'ah, there is no harm in him performing the prostration and what comes after it; he performs the prostration and the final tashahhud, then he says the taslim and performs the prostration for forgetfulness, or he performs the prostration for forgetfulness before saying the taslim. However, if the prostration was from a rak'ah before the last one, then the rak'ah in which he left it out is invalid, and he must perform a complete rak'ah in its place, and he performs the prostration for forgetfulness. Yes.

The presenter:
May Allah reward you.
