The ruling on the prostration for forgetfulness when in doubt about the number of prostrations

Question:
In itself, there is no authentic evidence. May Allah reward you with good. So how should our brother, who is the imam, act? The imam does not act in any way. The imam continues in his prayer. The discussion is only with that man who came and entered with him. May Allah reward you with good. We ask: Is the prostration for forgetfulness required of me? If he was silent regarding the number of prostrations, or forgot a prostration? Yes. Is the prostration for forgetfulness required of me? If you are in doubt about the number of prostrations you performed, or forgot a prostration?

Answer:
Yes. The default regarding a pillar is that it must be performed. And if one is in doubt about its performance while in the midst of the prayer, then the doubt in it is like leaving it. If one is in doubt about leaving a pillar, it is as if he left it.
So he must perform a prostration, and if he intends to pray, he prostrates for forgetfulness, because the prostration for forgetfulness is prescribed for forgetfulness. But if he did not perform it and prostrated for forgetfulness, is that sufficient? That is not sufficient; because it is considered established for the pillar, does his prayer not become valid?
And if the time is recent, he stands and performs a complete unit of prayer, and prostrates for forgetfulness afterwards if he intends to prostrate, because the one who is in doubt about leaving a pillar, the majority is the standard. May Allah reward you with good. After thanking Allah, Glorified and Exalted is He, for your generosity in answering the noble listeners, and hoping that the meeting will be renewed and that you are in good health.
