If I forget any prostration in one of the rak'ahs and remember it after two rak'ahs, am I required to repeat the entire prayer or perform the prostration for forgetfulness?

The questioner : The question states: If I forget any prostration in one of the rak'ahs and remember it after two rak'ahs, am I required to repeat the entire prayer or perform the prostration for forgetfulness? Please inform us of this. May Allah reward you with good.

The Shaykh : If a person forgets a prostration in one of the rak'ahs, then when he reaches the place of that prostration in the following rak'ah, he stands in the following rak'ah in the place of the first rak'ah. For example, if he left out the prostration from the first rak'ah, then when he reaches the place of the prostration in the second rak'ah, the second rak'ah becomes the first rak'ah, and he completes the rest of his prayer with it, and he performs the prostration for forgetfulness.

The questioner : Yes.

The Shaykh : Yes, but if he did not know that he had left out the prostration until after he had completed the prayer with the taslim, then if it was recent, he performs a rak'ah, then says the taslim, then performs the prostration for forgetfulness and says the taslim. And if he did not remember it recently, meaning if a long time had passed, it is obligatory for him to repeat the entire prayer.

The questioner : Yes, this is a message we received from Salem Ghanim.
