Question : But is it recommended? Or is it not?
Answer : The correct view is that it is recommended. He should prostrate if he omitted it out of forgetfulness. Because it is a prescribed statement. It is compensated for with the prostration for forgetfulness. And the prostration for forgetfulness does not become obligatory, because the original act for which prostration was required is not obligatory, so the branch does not become obligatory.
