What does the one who joins the prayer late do if the imam forgets in the prayer

The questioner : Yes. Peace be upon you.

The Shaykh : And upon you be peace.

The questioner : Is the question over the phone? Honorable Shaykh Muhammad Salih ibn Uthaymeen? I love you for the sake of Allah, O Shaykh.

The Shaykh : May Allah love you for the sake of which you loved us.

The questioner : May Allah reward you with good. Amen. O Shaykh, I caught, I caught the 'Isha' prayer with the imam in the second rak'ah. Yes. And the imam forgot in the prayer. Yes. And he performed the prostration for forgetfulness after the taslim. Yes. So what, what do I do?

The Shaykh : You do this: when he says the taslim from the prayer.

The questioner : Ask, yes.

The Shaykh : When they say the taslim from the prayer, you stand up to make up what you missed.

The questioner : Yes.

The Shaykh : And you do not prostrate with him. Then, when you have finished your prayer, if you had caught the forgetfulness with the imam, you prostrate after the taslim. And if the imam forgot before you joined him, you have no prostration for forgetfulness.

The presenter : May Allah reward you with good, peace be upon you. May Allah keep you safe. Peace.
