Is it valid for the imam to perform the prostration for forgetfulness before the closing salam if his obligatory prostration is after the salam?

Question:
The questioner says: Does the imam perform the prostration for forgetfulness before the salam if his obligatory prostration is only after the salam, in order to prevent confusion among the worshippers?

Answer:
O brothers, the prostration for forgetfulness is permissible before the salam and after the salam, absolutely, with no distinction. It is permissible, but the best, the best, is that if it is due to a deficiency, it is done before the salam, and if it is due to an addition, it is done after the salam. This is the best. Yes.
