The ruling on one who is uncertain about the number of prostrations

Question : The questioner says: If a person prostrates in the first prostration, then raises his head to sit between the two prostrations, and then forgets whether it was the first or the second prostration, what should he do?

Answer : We tell him: If it is more likely in your mind that the prostration from which you stood up was the second prostration, then you act according to that which is more likely in your mind and prostrate two prostrations after the closing salam. However, if that is not more likely in your mind and you are uncertain whether the one from which you stood up was the first or the second prostration, and you have no preference, then you consider it the first prostration, sit, and prostrate. When you have finished the tashahhud, you prostrate two prostrations for forgetfulness before the salam. Yes.
