Is prostration required for intentionally omitting or performing an action in prayer?

Primary text

Prostration is not legislated for an act omitted or performed intentionally. This position is held by Abu Hanifa. The evidence rests on the fact that the prostration is attributed specifically to forgetfulness (sahw), as indicated by the text stating, "If one of you forgets, let him prostrate two prostrations." The expiation of forgetfulness does not necessitate the expiation of intentional acts because the person is excused for forgetfulness but not for intentional deviation. Furthermore, the argument for analogy fails when considering additions of a pillar or a rak'ah, or standing where one should sit, or sitting where one should stand, for which prostration is not legislated.
