What is the ruling on one who makes a mistake in his prayer and performs the prostration for forgetfulness after the closing salam?

Question:
May Allah reward you with good and do you well. He says in another question: Sometimes during my prayer, I make a mistake, and then I intend to prostrate, but I make a mistake again and say the closing salam without performing the prostration for forgetfulness. Is my prayer valid? And is it valid to perform the prostration for forgetfulness after the closing salam? May Allah reward you with good.

Answer:
Yes, your prayer is valid. If you did not prostrate before the closing salam, you prostrate after the salam and do not leave the prostration. In fact, the prostration after the salam may be better. The prostration for forgetfulness is divided into two categories. The first category is prostration for a deficiency that occurs in the prayer, and its preference is before the salam. The second category is prostration for an addition to the prayer that is not of its kind, and its preference is after the salam. If he performs the entire prostration before the salam, or performs it all after the salam, that suffices him, and praise be to Allah. Yes.
