Is the addition of stoning to lashing for a married adulterer a case of abrogation (naskh) or specific exception (takhsis)?

Primary text

The application of stoning alongside lashing for the married adulterer is a specific exception (takhsis) of the general ruling of lashing, not an abrogation (naskh). This specific application is permissible without dispute, as general rulings of the Quran are frequently subject to specific exceptions. Even if it were considered abrogation, it would be abrogated by the text mentioned by Umar ibn al-Khattab.
