May one establish the last sunnahs of dhuhr and ‘isha prayers as four rakats?

One may establish the last sunnahs of dhuhr and ‘isha prayers in two or four rakats because there are narratives stating that the Prophet Muhammad (saw) established the last sunnah of dhuhr prayer in four rakats and advised it (Abu Dawud, Tatawwu’, 7; Tirmidhi, Salat, 205) while other narratives express that he established it in two rakats and also advised it (Bukhari, Tahajjud, 29, 34; Abu Dawud, Tatawwu’, 1). However, as the narratives which support that he established it in two rakats are stronger and more famous, this opinion is preferred and the general practice has been placed accordingly.
