What is the ruling if one forgets in the prostration for forgetfulness?

The questioner : But if one forgets in the prostration, it is a temptation, O Rashad.

The Shaykh : I mean, he prostrated the first prostration, then he doubted whether it was the second or the first? He builds upon his predominant suspicion; it is obligatory for him to perform the prostration for forgetfulness. He builds upon certainty, upon his predominant suspicion. If it is more likely in his mind that it was the first, he performs the second. If it is more likely in his mind that it was the second, he is finished. And if he builds upon certainty, as I said, he performs the second prostration. But does he prostrate for this forgetfulness? Yes, yes.

The questioner : That he does not prostrate. Because if he forgets a lot, he prostrates only two prostrations. If he forgets once, it is considered one forgetfulness.

The Shaykh : But this forgetfulness occurred after the prostration for forgetfulness. Yes, if multiple causes gathered, as I said, one prostration suffices for him.
